You have to hand it to John Kerry. Few people have the stick-to-it-iveness of our fair Secretary of State. Say what you want about the man, but when he commits to something, no matter how undeniably stupid, the man stays true to his commitment.
Even in the face of overwhelming evidence that Iran (1) has no intention of signing any sort of nuclear non-proliferation agreement and (2) persists in believing it would be best if the United States was obliterated from the face of the Earth, John Kerry is still trying, desperately, to make friends. He's like that girl at the slumber party who happily ignores that her training bra ended up in the freezer overnight because she's so desperate to be included. I almost feel sorry for him, if I wasn't 100% sure that this is all going to end terribly for either us or our allies (or both).
