His mind was made up before he was elected, Obama did it..... So he hates it.
When Iran develops nukes now, Is America suppose to protect Israel from Iranian attack? Yes or no?
1) Obama was an obvious supporter of Islamists across the ME. His policy decisions consistently supported their interests. He fairly drooled when Morsi took over Egypt. That, of course, was a failure.
2) The point is to prevent Iran from developing nukes. With this agreement, they can resume their program within a very short time and lose nothing.
