Foreign Policy 101
The brilliant Charles Krauthammer has detailed the last 3 experiments of US foreign policy in the last fifteen years. I can not overstate what an amazing must read this is for anyone who desires to argue foreign policy ideology in an intelligent manner.
Here's a lighter quote from Churchill that made me laugh out loud.
In the absence of omnipotence, one must deal with the lesser of two evils. That means postponing radically destabilizing actions in places where the support of the current nondemocratic regime is needed against a larger existential threat to the free world. There is no need to apologize for that. In World War II we allied ourselves with Stalin against Hitler. (As Churchill said shortly after the German invasion of the U.S.S.R.: "If Hitler invaded hell I would make at least a favorable reference to the devil in the House of Commons.") This was a necessary alliance, and a temporary one: When we were done with Hitler, we turned our attention to Stalin and his successors.That was just a crumb people, go get that cookie. Your brain will be bigger for it.
