That depends on what numbers you're going to believe about civilian fatalities in Iraq, Afghanistan, Yemen etc.
It is often claimed that the Iraq War killed anywhere from 0.5 million to over 1.0 million Iraqis.
However these big numbers don't make much sense considering that large scale aerial bombings and artillery strikes stopped after a month into the war and large-scale ground operations stopped after the second battle of Fallujah in 2004. The Iraqis then suffered a horrific decade of weekly and monthly sectarian terror attacks. However adding all the civilian fatalities from the US invasion and the decade of sectarian violence still doesn't add up to ~100,000 and not anywhere near the "millions" range.
Don't get me wrong. The people who started the Iraq War are war criminals. However it doesn't make sense to compare the most widely exaggerated estimates from the 10+ year Iraq War with the current UN confirmed counting of civilian fatalities in the 5 month war in Ukraine. If we go by confirmed civilian fatalities Russia is currently killing Ukrainian civilians at a faster pace than anytime during the Iraq War.
