I basically agree, except the US invasion of Iraq is far more defensible than the Russian invasion of Ukraine.
The USA got rid of a really bad dictator in Iraq. Ukraine's government was democratically elected and much better.
The USA did not annex Iraq (directly or by proxy), take Iraq's oil or establish permanent military bases in Iraq. Putin has explicitly said he sees Ukraine as part of a new Russian empire.
Let's assume the US had better intentions toward Iraq than Putin has towards Ukraine. But the people of Iraq are not thankful for the results of the US invasion. It did not bring peace and prosperity to Iraq.
