Iran's leaders (and a good deal of his cabinet) are members of the "Twelver" sect of Shiite Islam, who believe they need to help facilitate the return of the 12th or "Hidden" Imam - which is Islam's version of The Rapture, Second Coming, and apocalypse.
To help this happens, a large-scale, cataclysmic bettle between good and evil needs to start. Then the Imam returns, evil is vanquished, and paradise happens.

needs to have access to nuclear weapons.
