Well, Iran has had about 10 years to refine and make bombs.
As far as I know they haven’t tested yet. I’m sure they are getting help from the Norks. Perhaps the last test was theirs.
As long as Iran has a bomb, they will not use it directly. Iran has always fought wars by proxy. They will give a bomb or two to Hezbollah, or Al’Qaeda, and a city will go up.
The thing that worries me the most are small aircraft, and boats. Would not take much to carry it on a small rubber raft some miles offshore at night into a big port city. Like Seattle, or San Francisco, New York, DC, etc.
I suspect that this is SA’s way of making it clear that the Obama Admins approach is unacceptable. They don’t trust him and neither should we.
