The Ayatollah Seyyid Hosseini Khameini, the Supreme Leader of Iran, said that Iran will not develop nuclear weapons because this is contrary to Islamic teachings.
I believe him. The reason that I believe him is that Saddam Hussein’s Iraq used chemical weapons, including mustard gas and nerve gas, in his 1980-1988 war against Iran, and Iran never developed or used poison gas of its own.
The then Ayatollah Ruhbollah Khomeini ruled that use of chemical weapons, and also nuclear weapons were contrary to Islamic law. Instead Iran defended itself against the invaders by sacrificing its young men in human wave attacks.
When I consider the history of how the United States developed and used atomic weapons, and our “balance of terror” strategy during the cold war, I cannot imagine my government behaving with such restraint under such circumstances. In fact, if I were an Iranian leader today, threatened with attack by war hawks in the USA and Israel, I would want nuclear weapons as a deterrent.
I think Iran’s ayatollahs have earned the right to be believed on this issue.
