But we have more to be grateful for than this one villain’s demise. We must give thanks for something broader: The war on terror is over. I don’t mean that there is no threat of further jihadist attack. In the short term, the threat may even rise. I don’t mean that we should abandon all efforts at tracking terrorist cells. Of course not. But the war on terror was a way of seeing the world, explicitly modeled on World War II and the Cold War. It suggested that the struggle against “radical Islam” or “Islamofascism” or “Islamic terrorism” should be the overarching goal of American foreign policy, the prism through which we see the world.

I remember how seductive that vision was in the aftermath of 9/11. It imposed order on the world and gave purpose to American power. But it was a mistake from the start. Even the Cold War was a dangerously overblown vision, which blinded American policymakers to the fact that much of what happened in, say, Vietnam or Angola, had little to do with Moscow or communism. But the war on terror was worse. It made East Asia an afterthought during a critical period in China’s rise; it allowed all manner of dictators to sell their repression in Washington, just as they had during the Cold War; it facilitated America’s descent into torture; it wildly exaggerated the ideological appeal of a jihadist-Salafist movement whose vision of society most Muslims find revolting.
