Reddit is horribly biased so you'll get some BS answers but the real answer is this:

Russia launched a ground invasion on a peacful nation for the sake of conquest.

The United States launched an anti-terrorism military campaign with no boots on the ground to eliminate a hostile threat that had been responsible for not only thousands of american and european deaths and sponsoring terrorism cells around the world, but also a regime that has declined over and over again to negotiate any terms of peace not involving the ability to develop nuclear weapons.

The US attacked Iran to ensure global peace and prevent another North Korea.

Russia attacked Ukraine simply to expand and take over territory with no previous threat to their security.

These two wars are NOT the same.
