Obama had to think of this country first. What was best for us. We are his primary responsibility and interest, not Israel - and I'm not meaning that in any nasty way. It's a fact. America and our interests come first.
Obama could not push for a better deal any more than a Rep' could have. Iran after all has a leader with a mind of his own and no reason to buckle under to the wishes of a foreign nation.
I believe people should be glad an armed conflict was avoided with that nation.
