NY and Rome are their targets.
The Iranians are hoping they can keep on stalling the US until they can create a deliverable nuclear weapons system that will threaten Europe or even America. After that they hope to surreptiously place bombs in America, Israel and European countries and suddenly strike without warning.
The Iranians are not concerned about the repercusions of this plot because they hope to have the threat of a Russian and Chicom all-out nuclear response hold back any American nuclear retaliation. In addition, they hope to divert our attention even further by having their communist allies in South America stage some distracting military activity against our interests in that part of the world or even against our southern border. Also our Pacific forces will be pinned down by North Korean action against South Korea and Chicom aggression against Taiwan or even Japan. The Mullahs are crazy enough to think they can pull this off.
