Based on @Gonzo's Timeline Follow the Money: Fear and Loathing in Mecham's America, what if the United States would have declared war on the Islamic Republic of Iran in the 1980s? The president does not have to be necessarily Evan Mecham/Ronald Reagan/George H.W. Bush to achieve this. Would Desert Storm still happen as OTL? The Soviet Union could not interfere on Iran's side because they would be tied down in Afghanistan.
