Your desperation is showing.
If you're looking for the exact quote "worst country in the world," okay, that's pretty hard to come by from anybody famous, or outside a university. Stanford is where I heard it plenty of times, but not from anybody you'd know. The opinion is out there on the Web if you look for it, but again, not from anybody important. If you want to hug that as a victory like an old stuffed animal, go for it.
This view is not that uncommon though (article written a few months after 9/11):
But in the wake of September 11 there erupted something more primal and reflexive than criticism: a kind of left-wing fundamentalism, a negative faith in America the ugly.
In this cartoon view of the world, there is nothing worse than American power—not the woman-enslaving Taliban, not an unrepentant Al Qaeda committed to killing civilians as they please—and America is nothing but a self-seeking bully. It does not face genuine dilemmas. It never has legitimate reason to do what it does. When its rulers' views command popularity, this can only be because the entire population has been brainwashed, or rendered moronic, or shares in its leaders' monstrous values.
The reflex to attack America first in any issue is quite real. Heck, you're a prime example.
