Obama is never able to put together coalitions for deals. Remember that Asian deal they were supposed to get? Obama tried to scramble when he went to Asia to get it but it was a bust.
Memories of Bush's speech to the UN and he following achievements now come to mind. First Bush got his vote in Congress. Then he went to the UN and got his vote there. Powers is scrambling now because she's up against the Bush record. Will Obama's UN speech achieve the same results as Bush's? Doubt it. Obama has done nothing to work with these countries; why should they commit to him?
I doubt it too.
0bama is not respected in the world whether the countries are allies or adversaries, he's made a mess of foreign relations and is not trusted.
