The Tangerine Tyrant has declared that if Iran doesn't make a peace deal with him by the end of today 'a whole civilisation will die'... which one might interpret as a threat of a nuclear strike, or if it is a threat to be fulfilled by conventional weapons, requires either something akin to the carpet bombing of WW2 or (perhaps more likely) this will be a threat that if Iran ignores will not produce the apocalypse that has been threatened.
