So they can nuke someone. Duh. Here’s the latest fatwah out of Iran:

The spiritual leaders of the ultra-conservatives [in Iran] have accepted the use of nuclear weapons as lawful in the eyes of the shari’a. Mohsen Gharavian, a disciple of [Ayatollah] Mesbah Yazdi [who is Iranian President Ahmadinejad’s spiritual mentor], has spoken for the first time of using nuclear weapons as a counter-measure. He stated that ‘in terms of the shari’a, it all depends on the goal.’

Ah. Well, as long as you have a good reason, I suppose it’s ok…
