They’ll be used locally and the likely targets will be in Iran and SA. They can always kill Jews later, after they’ve conquered each other.
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.
