Mark my words, this crying out for peace is a ploy so that when they do something despite it, he can gain support and call for a brutal retaliation. Watch him nuke them... Or worse.
In fact, he'll probably say, "Look, they're building a nuke themselves, it's now or never!" And we get to watch as Israel uses Obama to blow away its only real enemy that's left.
I wouldn't be surprised at all if the nuclear weapon they're supposedly building turns out to be a lie, or the crisis that leads to Obama's Annihilation of Iran, turns out to be a lie, or provoked, or both.
