America is losing the longest war in its history. An enemy that had comprised a couple of hundred desperate men hiding in caves in eastern Afghanistan when the “war on terror” got underway following the 9/11 attacks is incarnated today as 20,000 fighting men in the Islamic State movement. And far from hiding in caves, ISIS has brazenly raised its black flag over vast swaths of territory in Syria and Iraq – countries that, in 2001, had been two of the most secular societies in the Middle East.Thus the fruits of the trillions of dollars and thousands of American lives – and hundreds of thousands of unnamed innocent civilians in the Middle East and Asia – devoured by the war on terror, which the Obama administration now says could rage for another 30 years.Given its costs, consequences and failures, the war on terror has provoked remarkably little sensible public debate in the U.S.
