Obama: Libya disaster was a great mistake I regret.
I hate to say it, but the last US President who had any real talent and skill in the area of foreign policy was Richard Nixon, even if he was corrupted and compromised. None of his successors could really measure up to his knowledge and experience.
Carter was a good man, but he seemed too naive and ill-prepared to deal with the world.
Reagan was senile and stupid. Bush Sr. should have had some understanding of the world as former head of the CIA, but he was a spoiled rich kid and an out-of-touch elitist.
Clinton, Bush Jr., Obama, Biden were all products of political machines. They're great for photo ops and kissing babies, but when it came to doing man's work, they were clearly amateurs.
That's how US politics seems to work. The political machines usually find some "pretty boy" or "pretty girl" - usually someone who is charismatic, popular, and can carry themselves on stage or TV (like an actor or newscaster). But it can't be anyone who is too smart or anyone who might think for themselves. That seems to be the M.O. these days.
