And totally wipe out his country.
That's been done before. During the Korean War, the American Air Force repeatedly bombed North Korea and destroyed everything. Literally every town, port, building, bridges were bombed to smithereens. The Americans stopped bombing because there were no more structures left to bomb, and planes were dumping bombs into the ocean before returning to base. The Norks recovered (with Chinese and Russian help). The North Koreans will hide underground during bombings, and come out to rebuild again. Best bet is to kill their leaders and force a change in their culture - hard to do with the Chinese involved.
