I dunno rodguy. The goal is to disrupt as much as possible without military intervention.
Ahmadinejad is in trouble at home. He's in trouble with the Europeans.
He canceled his trip to the UN because even the Russians will vote for sanctions.
(note- he must be late on payments. heh)
That said, we know that in UN speak, rules are very nice but they aren't supposed to be enforced, especially if it cuts off the flow of bribes.
He's upping the ante because a stable and democratic Iraq is the biggest threat to what he wants Iran to be. He's desperate to get Iraq back to the way it was.
It's less the surge than the change to the rules. He was supposed to have immunity, as would his generals, and it's gone now.
He doesn't have limitless resources. We don't either and it's good to leverage ours to undermine his.
