Three separate terror attacks on the very same morning—perhaps 37 people rifled to death on a Tunisia beach, a businessman decapitated outside a gas factory in France and a Shi’ite mosque bombed in Kuwait City—sounds like more than a coincidence. Simultaneity has been a signature of al-Qaeda since Aug. 7, 1998, when the U.S. embassies in Kenya and Tanzania were hit by truck bombs within minutes of each other. And if counterterrorism analysts say the greater threat now appears to be ISIS, sure enough the Islamic State in Iraq and Greater Syria’s spokesman Abu Mohammed al-Adnani just this week issued a general call for attacks in an audio message:
But while the extremist group claimed responsibility for the Kuwait bombing—a rare attack in a rich kingdom that has largely escaped terror—ISIS has so far said nothing about the other two. There’s a very real chance that the timing of the three attacks was indeed coincidental—though the reason is scarcely less alarming. The fact is there are so many terror attacks these days that three bad ones happening on the same morning falls well within the realm of statistical probabilities.
There were 13,463 terror attacks across the globe in 2014, according to the U.S. State Department. That factors out to an average of 1,122 a month, or about 37 a day, which means a terror attack roughly every 40 minutes, somewhere in the world. Half of them took place in Iraq, Pakistan and Afghanistan, where such atrocities have indeed grown so routine as to rarely qualify as international news. Syria, India and Nigeria together accounted for a bit better than a tenth of the sum. The rest were scattered around the globe, but not evenly. Of the 32,727 people killed, only 24 were Americans, or .07 percent of the total. Ten of those were in Afghanistan.
We are, moreover, in what has historically been the peak season for terror strikes, which past tallies show tend to rise in May, June and July. The holy month of Ramadan also factors in, with its associations of heightened piety. ISIS’s call to arms for Ramadan echoed similar summons from earlier insurgent groups in Iraq, where, as anyone who spent time in Baghdad over the last decade or so can attest, Fridays were seldom quiet.
If it seems like things are getting worse fast, they are. The number of attacks almost doubled from 2013 to 2014, as did the number fatalities. This had the perverse effect of making terror—which is meant to shock—actually less remarkable, as each attack dissolved into the generalized “background noise” of global news cycles.
ISIS has responded by amping up the horror. The group last year accounted for 17 percent of all terror strikes, yet nonetheless dominated the news by taking lives grotesquely and on video: Decapitating hostages, setting a Jordanian pilot alight in a cage, and in a new atrocity video released this week, killing captives by drowning them in a cage lowered into a pool; firing a rocket-propelled grenade at a car in which they are shackled; detonating explosive necklaces looped around their necks.
The group also wallows in mass killings, usually of Shi’ite Muslims and other groups the Sunni extremists of ISIS regard as apostates. Organized terror strikes by ISIS outside its theatre of military operations in Iraq and Syria remain infrequent, but when they come they do tend to be against Shi’ite targets, like the mosque in Kuwait City that ISIS dubbed “a gathering of apostates.” And as details emerge from rural France, where both suspects were taken alive, that attack may also turn out to have been inspired by, if not quite organized by ISIS. With a human head perched on a factory fence, the incident has the medieval flavor of the Islamic State.
The Tunisia attack, on a pair of beach hotels popular with European tourists also resulted in an arrest, of a man from the Tunisian city of Kairouan who had hidden a Kalashnikov in a beach umbrella. There were no immediate claims of responsibility, but both the targets and the setting— a moderate and democratic Arab nation friendly to the West—meant that attack is likeliest to hit closest to home for Americans. The dead included British, German and Belgian visitors, according to reports.
The U.S. remains at once quite safe and yet more vulnerable than it’s been in a decade, according to authorities. Officials explain the paradox by noting that the surge in the number of attacks worldwide includes few of the “spectacular” strikes such as bombings of civilian airlines, or other plots that the West in particular has hardened itself against. But officials expect more and more of the kind of attacks ISIS calls for — small-bore, lone-wolf, often impulsive attacks that may be impossible to detect in advance.
“In many ways I would say the threat streams now are higher than they’ve been since any time after Sept. 11,” Rep. Peter King, a New York Republican who serves on the House Intelligence subcommittee, tells TIME, speaking before Friday’s attacks. “ISIS has added a whole new dimension to it.”
The group’s power to inspire attacks, largely through its adept use of social media, has intelligence and counter-terrorism authorities scrambling to discern threats that could pop up anywhere a laptop or smart phone connects to the Internet. It’s a far more diffuse threat than Western countries faced from al-Qaeda, which organized specific plots through a rigid hierarchy, notes Jane Harman, formerly ranking Democrat on the Intelligence Subcommittee, now director of the Wilson Center in Washington. “A terror cell [now] is somebody on the web encountering some dangerous information,” Harman says. “That’s a terror cell.”
