The phenomenon of Australian jihadists fighting in the Middle East took a disturbing new turn last week when photos of a Caucasian man in mujahedin fatigues holding decapitated heads were posted on Twitter.
It follows the uploading last month of a YouTube video by the extremist Sunni group known as the Islamic State of Iraq and Greater Syria (ISIS) of two men with thick Australian accents calling on Westerners to join their violent quest to create a Muslim caliphate.
One of the pair, a teenager from Melbourne identified in the video as Abu Bakr al-Australi, later detonated an explosive belt in a crowded Baghdad marketplace, killing five people and wounding 90 more. He was the second Australian suicide bomber praised by ISIS in recent weeks; an estimated 200 Australian jihadists are currently fighting in Syria and Iraq.
The figure puts Australia in the unenviable position as the highest foreign per capita contributor to the conflict in the Middle East, and providing the largest contingent of foreign fighters from a developed nation. And there are fears that the worsening conflict in Gaza will only prompt more radical young Muslims to enter the fray.
“The government is gravely concerned by the fact that Australian citizens are heading to Iraq and Syria not only to fight but to take leadership roles,” Australia's Foreign Minister Julie Bishop said in parliament last week. She paused before adding, “There's a real danger that these extremists also come back home as trained terrorists and pose a threat to our security.”
The man holding the decapitated heads in the Twitter feed turned out to be Khaled Sharrouf, a boxer from Sydney who was jailed for four years in 2005 for his role in planning the most serious terrorist plot Australia has ever seen. Despite his notoriety, Sharrouf managed to flee while on parole in January by using his brother's passport to board a flight from Sydney to Southeast Asia from where he made his way to Syria.
The security breakdown has made Canberra redouble efforts to protect the nation from jihadists in the event they return home. Earlier this month, the attorney general's office added ISIS to its list of terrorists organizations, making it a crime for an Australian to join them punishable with up to 25 years imprisonment.
On advice from intelligence agencies, the Foreign Ministry has canceled the passports of 40 Australians suspected of extremist links. More than $700 million in additional funding will be injected into customs and border patrol over the next six years. In 2015 the service will be streamlined under a tough new national-security agency named the Australian Border Force.
Professor Gary Bouma, acting director of the Global Terrorism Research Centre at Melbourne’s Monash University, agrees that returning jihadists pose “a very serious problem, as they will be ideologically energized.” But he adds some will have been pacified after witnessing the “hideous gore of battle and the unrighteousness of all sides.”
“The first thing that needs to happen is those people need to be reintegrated into society,” Bouma says. “That means counseling, getting them a job and ensuring their cultural and social needs are met. It's a much healthier approach than isolating them.”
The leader of an Australian Muslim organization who spoke to TIME on condition of anonymity says calling foreign combatants in Syria “terrorists” was wrong, as many had gone there to protect family members from President Bashar Assad's repressive regime, which has unleashed torture, mass killings, starvation and chemical weapons upon Syrian civilians.
“The idea of them being terrorists just because they go to fight overseas, that is not a fair thing to say,” he says. “It's also unreasonable to say just because they fought in Syria that they're going to do the same thing when they come back home. There will always be one or two crazy fanatics among them, but they're a minority. They'd have to be really misguided to try something here.”
Another community leader, Samier Dandan, president of the Lebanese Muslim Association, has accused the government of double standards by outlawing those who fight in Syria while allowing others, namely members of Australia's Jewish community, to join the Israel Defense Forces (IDF).
“It's hard when you say something to one side, and they look and say 'How come we're not being treated the same?' The law should be across everyone,” Dandan told the Australian Associated Press.
However, Rafael Epstein, author of Prisoner X, a book about an Australian lawyer who fought with the IDF and worked as an operative with Israel's spy agency, Mossad, before going rogue, insists Dandan's comparison is flawed.
“What he is saying is someone who fights for Israel will be just as radicalized and have just as many [warring] skills to pose a security risk to Australia,” Epstein says. “But the values under which someone would fight for Israel, a democratic country with the rule of law, are very different to the values someone would fight for under ISIS, and they'd be much closer to Australia's values than ISIS's.”
Australian Prime Minister Tony Abbott agrees. “The best thing we can do … is to ensure that jihadis do not come back to this country,” he said last month.
Whether that will be enough to maintain Australia's record as one of the few major U.S. military partners in Afghanistan and Iraq to not have suffered a terrorist attack on its own soil remains open for discussion.
“U can't stop me and trust me if I wanted to attack aus [sic] I could have easily,” tweeted convicted terrorist Khaled Sharrouf in a message taunting Australian federal police posted from the battleground in Syria. “I love to slaughter use [sic] and ALLAH LOVES when u dogs r slaughtered.”
