Most people have no idea about the destruction produces by modern nuclear weapons. I believe that the Iranians want nukes as a diplomatic weapon as well as for status.
Once they get the nukes their leadership will be sorely tempted to use at least one on Israel by setting them off from a ship from a country that trades with Israel. People with the internationalist bent of Obama and Soros can not think through the problem. They may actually hope that the Israeli population will be so defeated that they will give up without a second strike.
If not then we are the world of a very confusing nuclear warfare game. Such a world is beyond the conceptions of lawyers and diplomats and US college students.
