As Trav points out, there's a bad week coming at the UN, with the Palestinians bringing forth requests and the US vetoing them, and unnecessary hysteria all around. A series of blunders by the Obama administration is largely to blame - blunders so bad that someone on either side of the Israelis vs Palestinians debate should be able to agree they were mistakes.
Mistake #1 - Giving a speech calling for a settlement freeze, and then, when presented with a resolution calling for a settlement freeze using the President's own wording, turning around and vetoing the resolution. The speech thoroughly disgusted the Israelis and Congress, the veto disgusted the rest of the world. Make up your mind before you give the flowery speeches.
Mistake #2 - When vetoing the settlement freeze, simultaneously issuing statements condemning settlement expansion, with lots of public hand-wringing. These statements completely cancelled any political or diplomatic credit for the veto that our President could have scored with Congress or the Israelis, respectively. If you're going to veto something, veto it, and keep any regrets to yourself.
Mistake #3 - Entering into a debate with a foreign prime minister (Netanyahu) in front of the US Congress. Huh? Is this how diplomatic negotiations are now conducted? And worse, it was a debate Obama should have known he'd lose. Don't let someone come into your house and pi$$ on you.
Mistake #4 - Giving a speech calling for a Palestinian state, including a target date, and then threatening to veto the resolution calling for a state, submitted on the target date, once more managing to make himself loathed by both sides. Again, make up your mind before getting all eloquent.
Mistake #5 - (In progress) Attempting to avoid a veto by strong-arming six members of the Security Council into abstaining. This fig leaf - actually more like a leaflet - might have given Obama some tiny amount of cover, if he hadn't gone and already announced his intention to veto. If the strong-arming is successful, supporters of the resolution still know he was against, and if it fails, he's got to use the veto anyway. Who knows when the bill for all the threats and promises made to those six countries will come due. Again, if you're going to veto something, just veto it.
Mistake #6 - (In progress) Taking the UN too seriously, and acting like this mostly symbolic UN Resolution is a matter of the gravest importance, thus adding to Israeli, evangelical, and congressional hysteria over the issue. Israel has ignored plenty of past resolutions, some of them (e.g. return of refugees) far more threatening than this one; adding another to the pile is not an existential threat.
Mistake #7 - (Purely domestic, but driving the previous six) Believing that there is anything he can do on this issue that will make Congress stop accusing him of throwing Israel under the bus. There isn't.
The pattern here is that of a person who got where he is through inspirational rhetoric, and thus overestimates its value. Also, a person who thought he could play both sides of an issue. A similar list of mistakes could be given for how the Arab Spring has been handled.
Pretty poor, even by Nobel Laureate standards.
