My one concern about Iran as a nuclear power is the possibility that a bomb could find its way into the hands of non-state terrorists. Beyond that, a nuclear Iran might provide some balance to the clearly nuclear Israel. Mutual assured destruction worked during the Cold War; perhaps it would work here to. And it is just possible that iran wants the respect from the west that comes, sadly, from being a nuclear power, and that it could actually use it responsibly. Certainly they have been, if anything, less bellicose than the Netanyahu crowd in Israel.
