I think Israel will strike Iran at some point during Barry's presidency because he believes in just talking (to crazy people who don't care about anything but force) and they know he will puss out or face losing our only ally in the region. If it happens we'll just divert forces from Iraq to Iran.
And how exactly is Israel going to attack Iran (or viceversa)?
If Israel attacks Iran WILL RETALIATE with a terror campaign the likes noone has seen. If the US gets involved, which is most likely the outcome, American cities will be attacked left and right, possibly with nukes (as per Scott Ritter). Iran has a population of 70 millions souls. Sixsty thousand of their
nutcases have already signed up for suicide operations. Their territory is "difficult" by all conventional war standards. If we attack, we will have to invade the country, which means we will not be able to contain it, which means that nukes will have to be used, which means Russia will eventually get into the action by taking out Israel first and then possibly going against the US (with China just waiting on the sidelines to pick up the pieces).
Yes America, let your libido do the talking and pretty soon we'll be running into a bunker because nukes are on the way.
That is a really smart thing to do.
