Obama: On Hallucinogens?

On Wednesday, Obama decided that our strongest/longest arab ally besides Saudi Arabia - Egypt - isn't an ally. In an attempt to make such a bizarre and dangerous statement look rational, Jay Carney offered an explanation, which, if taken seriously, would mean that Israel is not an ally.

Has the president lost his marbles? Is he too dumb to handle foreign policy? Perhaps he's just an ego maniac, and he figures he decides, on any given day, who our allies are - history be damned!
