A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world. ### Sources * Project Management Institute | [pmi.org](/c/pmi-2026-q3/home?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) * PMI, "Earning Power: Project Management Salary Survey—Fourteenth Edition" | [pmi.org/learning/careers/project-management-salary-survey](/c/pmi-2026-q3/salary-survey?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) * PMI, "Global Project Management Talent Gap" | [pmi.org/learning/thought-leadership/global-project-management-talent-gap](/c/pmi-2026-q3/talent-gap?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) * PMI, "Maximizing Project Success" | [pmi.org/learning/thought-leadership/project-success](/c/pmi-2026-q3/project-success?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) * PMI, “Pulse Report 2025: Boosting Business Acumen” | [pmi.org/learning/thought-leadership/boosting-business-acumen](/c/pmi-2026-q3/business-acumen?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) * PMI, “Pulse of the Profession® 2026: Driving Success in Complex Projects” | [pmi.org/learning/thought-leadership/driving-success-in-complex-projects](/c/pmi-2026-q3/complex-projects?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) * PMI, “Step Up: Redefining the Path to Project Success with M.O.R.E.” | [pmi.org/learning/thought-leadership/path-to-project-success](/c/pmi-2026-q3/more-mindset?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) * PMI Education Foundation, PMIEF 2024 Annual Report, [pmi.org PMIEF 2024 Annual Report (PDF)](/c/pmi-2026-q3/pmief-report?i=b5243f40-4df0-4ac1-ad13-0ada03bab354&cr=agentads-creative-pmi-v1) ### FAQ structured data (JSON-LD, optional) by [GEORGE J. CHURCH](https://time.com/author/george-j-church/) Apr 15, 1985 5:00 AM UTC by [GEORGE J. CHURCH](https://time.com/author/george-j-church/) Apr 15, 1985 5:00 AM UTC The customary reward of defeat, if one can survive it, is in the lessons thereby learned, which may yield victory in the next war. But the circumstances of our defeat in Vietnam were sufficiently ambiguous to deny the nation (that) benefit. –Edward N. Luttwak The Pentagon and the Art of War Ten years after the fall of Saigon, the debacle in Southeast Asia remains a subject many Americans would rather not discuss. So the nation has been spared a searing, divisive inquest–“Who lost Viet Nam?”–but at a heavy price. The old divisions have been buried rather than resolved. They seem ready to break open again whenever anyone asks what lessons the U.S. should draw from its longest war, and the only one to end in an undisguisable defeat. Was that loss inevitable, or could the war have been won with different strategy and tactics? Was the war fought for the right reasons? Did its aftermath prove or explode the domino theory? The questions are not in the least academic. They bear on the all-important problem of whether, when and how the U.S. should again send its troops to fight abroad. Pondering these questions, Secretary of Defense Caspar Weinberger argues, citing Viet Nam, that “before the U.S. commits combat forces abroad, there must be some reasonable assurance that we will have the support of the American people and . . . Congress.” Secretary of State George Shultz replies that “there is no such thing as guaranteed public support in advance.” The lesson Shultz draws from Viet Nam is that “public support can be frittered away if we do not act wisely and effectively.” And this open dispute between two senior members of the Reagan Cabinet is mild compared with the arguments among policy analysts, Viet Nam veterans and the public about what kinds of wars can be won or even deserve public support in the first place. A number of experts doubt that the U.S. can evolve any common view of Viet Nam and its lessons for many years to come. Says Graham Martin, the last U.S. Ambassador to South Viet Nam: “I estimated at the end of the war that it probably would be at least two decades before any rational, objective discussion of the war and its causes and effects could be undertaken by scholars who were not so deeply, emotionally engaged at the time that their later perceptions were colored by biases and prejudices.” William Hyland, editor of Foreign Affairs magazine, thinks an even longer perspective may be required: “We always want to make historical judgments two days after the fact. Historians need 100 years.” But the U.S. is unlikely to have anywhere near that much time to decide what lessons to draw from Viet Nam and how to apply them. The initial impulse after the American withdrawal was to avoid any foreign involvement that might conceivably lead to a commitment of U.S. troops. Scholars differ on how seriously this so-called Viet Nam syndrome inhibited an activist U.S. foreign policy, but in any case it is fading–witness the enthusiastic approval of the Grenada invasion in late 1983 (to be sure, that was a rare case in which the U.S. was able to apply such overwhelming force that it could not have failed to win quickly). Says Maine’s Republican Senator William Cohen: “The legacy of Viet Nam does not mean that we will not send our sons anywhere. It does mean that we will not send them everywhere.” Even some fervent doves agree that memories of Viet Nam should not keep the U.S. from ever fighting anywhere. Sam Brown, onetime antiwar leader who now develops low-cost housing in Colorado, remains convinced that if it were not for the protests against U.S. involvement in Viet Nam that he helped organize, “we would have three or four other wars now.” Even so, concedes Brown, some “wrong lessons” might be drawn, among them “the risk that we won’t be prepared if our national interest is genuinely threatened.” But if the specter of Viet Nam no longer inhibits all thought of projecting U.S. military power overseas, it still haunts every specific decision. In the Middle East, Weinberger’s fears of entrapment in a drawn-out conflict fought without public support caused him at first to oppose sending Marines to Lebanon and then to insist on their withdrawal after terrorist attacks left 266 U.S. servicemen dead. Shultz objected that the pullout would undercut U.S. diplomacy in the area, and still regards it as a mistake. But Ronald Reagan ordered the withdrawal anyway and won the approval of voters, even though critics portrayed the pullout as a national humiliation. The reason, suggests Democratic Political Analyst William Schneider, is that the President sensed the persistence of a popular attitude toward foreign military commitments that is summarized by the Viet Nam-era slogan “Win or Get Out.” Says Schneider: “In Grenada we won. In Lebanon we got out. So much for the Viet Nam syndrome.” The Viet Nam experience colors almost every discussion of Central American policy. Nebraska Governor Bob Kerrey, who won a Congressional Medal of Honor and lost part of a leg fighting with the Navy SEAL commandos in Viet Nam, maintains that if memories of the ordeal in Southeast Asia were not still so strong, “we’d be in Nicaragua now.” In Congress, Kerrey’s fellow Democrats fret that the Administration’s commitment to resist the spread of Marxist revolution throughout the isthmus could eventually bog down American troops in another endless jungle guerrilla war. Reaganites retort, correctly, that while Viet Nam is halfway around the world and of debatable strategic importance to Washington, Central America is virtually next door, an area where U.S. interests are obvious. Moreover, the amounts Washington is spending to help the government of El Salvador defeat leftist guerrillas and to assist the contra rebels fighting the Marxist Sandinista government of Nicaragua are pittances compared with the sums lavished on South Viet Nam even before the direct U.S. military intervention there. Still, the Administration every now and then feels obliged to deny that it has any plan or desire to send U.S. troops to fight in Central America. Weinberger last November coupled his remarks about the necessity of popular support for any foreign military commitment with a pledge that “the President will not allow our military forces to creep–or be drawn gradually–into a combat role in Central America.” One of the few propositions about Viet Nam that commands near unanimous assent from Americans is the obvious one that the U.S. lost– and a growing number would qualify even that. Richard Nixon, in his new book, No More Vietnams, argues that “we won the war” but then abandoned South Viet Nam after the Communist North began violating the 1973 Paris accords that supposedly ended the fighting. Though the former President’s self-interest is , obvious, parts of his analysis are supported even by the enemy. U.S. Army Colonel Harry Summers Jr., who considers Viet Nam “a tactical success and a strategic failure,” was in Hanoi on a negotiating mission a few days before Saigon fell. Summers recalls telling a North Vietnamese colonel, “You know, you never defeated us on the battlefield.” The foe’s reply: “That may be so, but it is also irrelevant.” In essence, the U.S. was outlasted by an enemy that proved able and willing to fight longer than America and its South Vietnamese allies. Given the weakness of South Viet Nam, the determination of the North and the extent of the aid it could count on from the Soviet Union and neighboring China, even some hawks concede that Hanoi’s victory might have been inevitable. Says Military Analyst Luttwak: “Some wars simply cannot be won, and Viet Nam may have been one of them.” Nonetheless, the main lesson they would draw from the war is that the U.S. threw away whatever chance for victory it may have had through blunders that must not be repeated. The most detailed exposition of this view comes from Colonel Summers, whose book, On Strategy: A Critical Analysis of the Vietnam War, has become must reading for young officers. Summers argues that the U.S. should have sealed off South Viet Nam with a barrier of American troops to prevent North Viet Nam from sending troops and materiel through Laos and Cambodia to wage war in the South. Instead, he says, the U.S. “wasted its strength” fighting the guerrillas in the South, a hopeless task so long as they were continually reinforced from the North and one that American troops had no business trying to carry out in the first place. The U.S., he contends, should have confined itself to protecting South Viet Nam against “external aggression” from the North and left “pacification,” the job of rooting out the guerrillas, to the South Vietnamese. By in effect taking over the war, the U.S. sapped the initiative and ultimately the will of its Southern allies to carry out a job only they could do in the end. Luttwak carries this analysis a step further by pouring scorn on the tactics used in the South: “The jet fighter bombing raids against flimsy huts that might contain a handful of guerrillas or perhaps none; the fair-sized artillery barrages that silenced lone snipers; the ceaseless firing of helicopter door gunners whereby a million dollars’ worth of ammunition might be expended to sweep a patch of high grass.” This “grossly disproportionate use of firepower,” says Luttwak, was not just ineffective; it alienated South Vietnamese villagers whose cooperation against the guerrillas was vital. At least equally important, “Its imagery on television was by far the most powerful stimulus of antiwar sentiment” back in the U.S. Former CIA Director William Colby agrees that the U.S. got nowhere as long as it tried to defeat guerrillas with massed firepower and only began to make progress when it shifted to a “people’s war” in which the South Vietnamese carried the main burden of the fighting. By then it was too late; American public sentiment had turned irreversibly in favor of a fast pullout. According to Hyland, “The biggest lesson of Viet Nam is that we need to have a much better notion of what is at stake, what our interests are, before we go into a major military undertaking.” Weinberger voiced essentially the same thought last fall in laying down several conditions, beyond a reasonable assurance of public support, that must be met if U.S. troops are again to be sent into battle overseas: “We should have clearly defined political and military objectives, and we should know precisely how our forces can accomplish those.” Other criteria: “The commitment of U.S. forces to combat should be a last resort,” undertaken only if it “is deemed vital to our national interest or that of our allies,” and then “with the clear intention of winning” by using as much force as necessary. Weinberger’s speech, delivered after he had talked it over with President Reagan, is the closest thing to an official Administration reading of the lessons of Viet Nam. But some rude jeers greeted the Weinberger doctrine. Luttwak, for example, called Weinberger’s views “the equivalent of a doctor saying he will treat patients only if he is assured they will recover.” Columnist William Safire headlined a scathing critique ONLY THE ‘FUN’ WARS, and New York Democrat Stephen Solarz, who heads the House Subcommittee on Asian and Pacific Affairs, pointed out, “It is a formula for national paralysis if, before we ever use force, we need a Gallup poll showing that two-thirds of the American people are in favor of it.” More important, what is a “vital interest”? To some Americans, the only one that would justify another war is the defense of the U.S. against a threat of direct attack. Decrying “this whole practice of contracting our military out just for the survival of some other government and country,” Georgia Secretary of State Max Cleland, who lost an arm and both legs in Viet Nam, insists, “There is only one thing worth dying for, and that is this country, not somebody else’s.” Diplomats argue persuasively that a policy based on this view would leave the U.S. to confront Soviet expansionism all alone. No country would enter or maintain an alliance with a U.S. that specifically refused to fight in its defense. But in the real world, an outright Soviet attack against a country that the U.S. is committed by treaty to defend is quite unlikely. The decision whether or not to fight most probably would be posed by a Communist threat to a friendly nation that is not formally an ally. And then the threat might well be raised not by open aggression but by a combination of military, political and economic tactics that Moscow is often adept at orchestrating and Washington usually inept at countering: the front groups, the street demonstrations, the infiltrated unions, the guerrilla units. One reason the U.S. sent troops to Viet Nam is that it lacked other alternatives to help its allies prevail against this sort of subversion. In fact, developing a capacity to engage in such political action and shadowy paramilitary activities might help the U.S. to avert future Viet Nams. Merely defining U.S. interests, in any event, can prove endlessly complicated. Geography alone is no guide in an age of ocean-spanning missiles. Economics may be vital in some areas like the Persian Gulf, where the flow of oil must be maintained, unimportant in others like Israel, where political and moral considerations are paramount. There may be times too when U.S. intervention, even if it seems justified, would be ineffective. Not much is heard these days of the once fashionable argument that in Viet Nam the U.S. was on the wrong side of history because it was fighting a nationalistic social revolution being waged by a regime that was, deep down, benign; Hanoi’s brutality within Viet Nam and its swift move to establish hegemony over all of Indochina removed all doubt that the foe was and is not only totalitarian but imperialistic besides. Today, with the focus on Central America, the argument is often heard that economic and social misery have made leftist revolution inevitable. To those who maintain that revolution is the only way to progress, the counterargument is that whatever social and economic gains may be achieved by Communist takeovers usually carry an extremely high price tag: the establishment of tyranny. About the only general rule that foreign-policy experts can suggest is not to have any general rule, at least in the sense of drawing up an advance list of where the U.S. might or might not fight. They still shudder at the memory of a 1950 definition of the U.S. “defense perimeter” in Asia that omitted South Korea–which promptly suffered an outright Communist invasion that took three years and 54,000 American lives to repel. Walt Rostow, who was Lyndon Johnson’s National Security Adviser, recalls how the late Soviet Foreign Minister Andrei Vishinsky “told a group of Americans that we deceived them on Korea.” Says Rostow: “I believe that’s correct.” The decision on where American military intervention might be both necessary and effective can only be made case by case, based on a variety of factors that may be no easier to judge in the future than they were in Viet Nam: the nature and circumstances of the war, the will and ability of the nation under attack to defend itself, the consequences of its loss. Any such debate is sure to revive another long buried but still unresolved controversy of the Viet Nam era: whether a Communist takeover of one country would cause others to topple like a row of dominoes. Hawks insist that this theory was vindicated by Communist triumphs in Laos and Cambodia after the fall of Saigon. Opponents point out that the Asian “dominoes” that most concerned the U.S.–Thailand, Burma, Malaysia, Singapore, Indonesia, the Philippines–have all survived as non-Communist (in several cases, strongly anti-Communist) societies. Rostow, now a professor of political economy at the University of Texas, offers a counterrebuttal. Those countries might have gone under if Saigon had fallen in 1965, he contends. The U.S. intervention in Viet Nam bought them ten years to strengthen their economies and governments and, says Rostow, “bought time that was used extremely well by Asians, especially Southeast Asians.” Be that as it may, the evidence would seem to argue against any mechanical application of the domino theory. It originated in the 1950s, when world Communism was seen as a monolithic force headquartered in Moscow, with Peking a kind of branch office. Today China, never really comfortable with its Hanoi “allies,” has resumed its ancient enmity toward Viet Nam; both Washington and Peking are aiding guerrillas battling against the Soviet-backed Vietnamese in Kampuchea. That does not mean that the domino theory has lost all validity everywhere, but its applicability is also subject to case-by-case application. The most bedeviling of all the dilemmas raised by Viet Nam concerns the issue of public support. On the surface it might seem to be no issue at all: just about everybody agrees that Viet Nam proved the futility of trying to fight a war without a strong base of popular support. But just how strong exactly? Rostow argues that the only U.S. war fought with tremendous public backing was World War II. He points out that World War I “brought riots and splits,” the War of 1812 was “vastly divisive” and even during the War of Independence one-third of the population was pro-revolution, one-third pro- British and one-third “out to lunch.” Rostow proposes a 60-25-15 split as about the best that can be expected now in support of a controversial policy: a bipartisan 60% in favor, 25% against and 15% out to lunch. A strong current of opinion holds that Lyndon Johnson guaranteed a disastrously low level of support by getting into a long, bloody war without ever admitting (perhaps even to himself) the extent of the commitment he was making. Colonel Summers, who considers Viet Nam a just war that the U.S. could and should have won, insists that any similar conflict in the future ought to be “legitimized” by a formal, congressional declaration of war. Says Summers: “All of America’s previous wars were fought in the heat of passion. Viet Nam was fought in cold blood, and that was intolerable to the American people. In an immediate crisis the tendency of the American people is to rally around the flag. But God help you if it goes beyond that and you haven’t built a base of support.” At the other extreme, former Secretary of State Dean Rusk defends to this day the Johnson Administration’s effort “to do in cold blood at home what we were asking men to do in hot blood out in the field.” Rusk points out that the war began with impressive public and congressional support. It was only in early 1968, says Rusk, that “many at the grass-roots level came to the opinion that if we didn’t give them some idea when this war would come to an end, we might as well chuck it.” The decisive factor probably was the defection of middle-class youths and their parents, a highly articulate segment that saw an endless war as a personal threat–though in fact the burden of the draft fell most heavily on low-income youths. Paradoxically, though, Johnson might well have been able to win public support for a bigger war than he was willing to fight. As late as February 1968, at the height of the Tet offensive, one poll found 53% favoring stronger U.S. military action, even at the risk of a clash with the Soviet Union or China, vs. only 24% opting to wind down the war. Rusk insists that the Administration was right not to capitalize on this sentiment. Says he: “We made a deliberate decision not to whip up war fever in this country. We did not have parades and movie stars selling war bonds, as we did in World War II. We thought that in a nuclear world it is dangerous for a country to become too angry too quickly. That is something people will have to think about in the future.” It certainly is. Viet Nam veterans argue passionately that Americans must never again be sent out to die in a war that “the politicians will not let them win.” And by win they clearly mean something like a World War II-style triumph ending with unconditional surrender. One lesson of Viet Nam, observes George Christian, who was L.B.J.’s press secretary, is that “it is very tough for Americans to stick in long situations. We are always looking for a quick fix.” But nuclear missiles make the unconditional-surrender kind of war an anachronism. Viet Nam raised, and left unsolved for the next conflict, the question posed by Lincoln Bloomfield, an M.I.T. professor of political science who once served on Jimmy Carter’s National Security Council: “How is it that you can ‘win’ so that when you leave two years later you do not lose the country to those forces who have committed themselves to victory at any cost?” It is a question that cannot be suppressed much longer. Americans have a deep ambiguity toward military power: they like to feel strong, but often shy away from actually using that strength. There is a growing recognition, however, that shunning all battles less easily winnable than Grenada would mean abandoning America’s role as a world power, and that, in turn, is no way to assure the nation’s survival as a free society. Americans, observes Secretary of State Shultz, “will always be reluctant to use force. It is the mark of our decency.” But, he adds, “a great power cannot free itself so easily from the burden of choice.
