Zer0 flunked the ME fact and history test.
But what's worse is that it's not just him. We know he's so vain and egotistical that he can't imagine that one of his august pronouncements will not be welcomed by all as pearls of the sagest wisdom.
It's that the entire WH seems to be either as ignorant as he is, or so fawning and subservient that no one was able to tell the anointed 0ne that the Israelis were going to have some problems with what he was proposing, and that maybe, under the current circumstances it might be better not to say it.
Even odder, the entire week leading up to the speech there were numerous contradictory leaks about what it would contain: some stories claimed that he was going to come out with new Israeli/Palestinian peace proposals, and others, often the very next day, would say that he wasn't going to address the Israeli/Palestinian problem at all. This can only point to the fact that the drafting of the speech was highly political with lots of jockeying, and handled the way this WH usually handles things, that is to say ineptly.
I'm guessing that no one at the State Dept., or even Hillary, actually knew what the boy wonder was going to say until a few hours before the speech. Otherwise, someone would have pointed out to him that there was going to be some huge political fallout. And of course, he didn't run it by the Israeli ambassador either, judging by the stories of Bibi's furious talk with Hillary (and who probably told Bibi that she was just as surprised as he was).
No, this fiasco has all the hallmarks of an 0bama solo project, entirely befitting the most brilliant mind ever to occupy the WH.
