There's no comparison at all. The vast majority of the people who died in Iraq were killed by other Iraqis in a sectarian conflict. Yes, it was sparked by the US invasion, and they definitely should be blamed for both invading in the first place and for fucking it up once they did, but American soldiers did not, with very very few exceptions, go around indiscriminately killing civilians and leveling cities block by block WW2-style, like the Russians did in Bucha, Mariupol, etc.
At an individual moral level maybe it’s worse for a soldier to kill civilians directly, than to kill them indirectly by overthrowing the government and destabilizing the health system. But if you’re comparing nations I think you have to look at a macro level, not at the level of individual morality. “Team America: World Police” foreign policy has a much higher aggregate body count than Russia’s territorial expansionist foreign policy.
