As August ended, American troops completed their withdrawal from Afghanistan almost 20 years after they first arrived. On the formal date of withdrawal, however, President Biden insisted that “over-the-horizon capabilities” (airpower and Special Operations forces, for example) would remain available for use anytime. “[W]e can strike terrorists and targets without American boots on the ground, very few if needed,” he explained, dispensing immediately with any notion of a true peace. But beyond expectations of continued violence in Afghanistan, there was an even greater obstacle to officially ending the war there: the fact that it was part of a never-ending, far larger conflict originally called the Global War on Terror (in caps), then the plain-old lower-cased war on terror, and finally — as public opinion here soured on it — America’s “forever wars.”

As we face the future, it’s time to finally focus on ending, formally and in every other way, that disastrous larger war. It’s time to acknowledge in the most concrete ways imaginable that the post-9/11 war on terror, of which the bombing and invasion of Afghanistan was the opening salvo, warrants a final sunset.

True, security experts like to point out that the threat of global Islamist terrorism is still of pressing — and in many areas, increasing — concern. ISIS and al-Qaeda are reportedly again on the rise in the Middle East, South Asia, and Africa.

Nonetheless, the place where the war on terror truly needs to end is right here in this country. From the beginning, its scope, as defined in Washington, was arguably limitless and the extralegal institutions it helped create, as well as its numerous departures from the rule of law, would prove disastrous for this country. In other words, it’s time for America to withdraw not just from Afghanistan (or Iraq or Syria or Somalia) but, metaphorically speaking at least, from this country, too. It’s time for the war on terror to truly come to an end.

With that goal in mind, three developments could signal that its time has possibly come, even if no formal declaration of such an end is ever made. In all three areas, there have recently been signs of progress (though, sadly, regress as well).

Repeal of the 2001 AUMF

First and foremost, Congress needs to repeal its disastrous 2001 Authorization for the Use of Force (AUMF) passed — with Representative Barbara Lee’s single “no” vote — after the attacks of 9/11. Over the last 20 years, it would prove foundational in allowing the U.S. military to be used globally in essentially any way a president wanted.

That AUMF was written without mention of a specific enemy or geographical specificity of any kind when it came to possible theaters of operation and without the slightest reference to what the end of such hostilities might look like. As a result, it bestowed on the president the power to use force when, where, and however he wanted in fighting the war on terror without the need to further consult Congress. Employed initially to root out al-Qaeda and defeat the Taliban in Afghanistan, it has been used over the last two decades to fight in at least 19 countries in the Greater Middle East, Africa, and Asia. Its repeal is almost unimaginably overdue.
