Eh.. realpolitik is short term and almost always misses the big picture. When things change, you wind up on the wrong side, like us with Mubarak right now. Or all that Taliban and Saddam funding once upon a time.
There's a balance of course.. but in a case like this, I'd elevate America the idea over America the set of short term interests, and I'm embarrassed by Biden's comments too.
Indeed. People will make you think that Realpolitik is some hard-thinking, tough-decisions geopolitical chess game. But it's not, it's just international checkers, making the least bad decision at the last minute because you haven't planned ahead. It's a shame that it has infected American foreign policy for so long.
Naive idealism is no better, but pragmatic idealism is far far better, but also far more difficult.
Ok. With Iraq in the list above I specifically meant the period when Saddam was being propped up by the US as an example of realpolitik, not the situation later on.
That said, "idealism" is also often a terrible basis for foreign policy as well.
