"What do you think Saddam Hussein's reaction would have been to developments within Iran regarding that country's nuclear programme?"

With or without a nuclear programme, Saddam feared Iran.

Not even the Sunnis of Iran supported Saddam. Without the support of the U.S., Saddam would probably have been crushed by Iran sooner or later. With or without nuclear weapons, Saddam was vastly outnumbered.

Thats why it was stupid for the U.S. to get involved. They should have let Iran take care of Saddam in the first place.
