MAD won't work when the other party is a nutcase. It depends on some values in common, like loving their children. Now who blows up their own kid and then talks their little brother into doing it too?
I wonder about the sanity of those who think MAD will work with the mullahs.
A recent military parade in Iran showed off their new missile forces. In the parade was a banner depicting an Iranian missile destroying Israel. Their 'elected' mullah leader has also openly called for the destruction of Israel. They really cannot make their intentions any clearer.
