You’re wrong. Churchill said we should have strangled the Bolshevik baby in its cradle. He tried. But war weary cynics and isolationist stopped him. Now, we need to do the same thing and stop ISIS before they create a genocidal revolution like the communists did.
Things are much worse over there than if we had left Iraq and Afghanistan alone. The track record of our military involvement is very poor. You simply can’t defeat a cultural/religious movement on its own turf unless you are willing to fund an indefinite occupation, or commit genocide yourself — which we fortunately aren’t willing to do.
