In an article for the Times of Israel, Saeed Ghasseminejad argues that the beliefs of important people in Iran are apocalyptic and hence, not rational. He strongly implies that they would be willing to use nuclear weapons, that they may be willing to die in a nuclear exchange with Israel or the U.S.
Ghasseminejad names names and points to relationships which suggest this kind of willingness. He makes an argument for bombing the c**p out of Iran, though he is careful to never say it explicitly.
