If Iran wants to fight, that will be the official end of Iran. Never threaten the United States again!

The first issue is that the US would need to destroy Iran's air defenses, including fighters and surface-to-air missiles, in order to ensure the bombs hit their targets and to prevent Iran from doing serious damage in response. According to Robert Farley, a professor at the University of Kentucky and an expert on air power, this "would involve long-range bombers, drones, electronic warfare, land-based fighter-bombers, carrier aircraft, and submarine-launched cruise missiles."

Such respect for the people of Iran as they try to take back their corrupt government. You will see great support from the United States at the appropriate time!
