The US has commited genocide against Koreans (both sides of the parallel), Vietnamese, Iraqi, Palestinian, and far, far more. The US is currently trying to topple Iran because Iran is refusing to play ball with the genocidal US Empire. The US Empire is by far the worst state on the planet, without it the fascist Entity engaged in current war with Iran would not exist and Palestine would be free.

This is extremely naive. Iran has its problems, but there's no comparison, the US is not a democracy and is the active creator of genocide around the world today. If Iran was toppled, conditions for Iranians and Palestinians would get far worse, not better.
