While al-Qaeda took advantage of the Internet’s “dark spaces” to recruit and instruct followers and to spread its message, the Islamic State (IS) has used the web and social media openly. Its beheading videos are the product of a carefully managed propaganda campaign, waged by means of technological innovations that allow its operatives to remain difficult or impossible to trace. In order to counter this threat, argues Robert Hannigan, head of the British intelligence agency tasked with monitoring electronic communication, governments will need the cooperation of the private sector:

I understand why [private technology companies] have an uneasy relationship with governments. They aspire to be neutral conduits of data and to sit outside or above politics. But increasingly their services not only host the material of violent extremism or child exploitation, but are the routes for the facilitation of crime and terrorism. However much they may dislike it, they have become the command-and-control networks of choice for terrorists and criminals, who find their services as transformational as do the rest of us. If they are to meet this challenge, it means coming up with better arrangements for facilitating lawful investigation by security and law-enforcement agencies than we have now.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
