You wouldn’t even have needed to in Iran after the mid 1980s, the mullahs lost support long ago after the reign of terror and war with Iraq.
Then the newly reverted Pro-Western Iran could go back to being the neighborhood’s cop, and the Saudis could have been told to go shove their Korans up somewhere unpleasant and stop spreading Wahabbism across the world.
As I recall, Obama did NOTHING to help an uprising about four years ago or so.
