Superman Incident
At some point, North Korea became a geopolitical enemy of the United States of America. It later developed nuclear-powered submarines.

In September 2021, Superman saved a crew on board a nuclear-powered submarine and returned it to North Korea. This caused a rift between him and Lieutenant Anderson of the Department of Defense as he viewed this action as aiding an enemy nation.
