You complain about whattaboutism then point out that Russia is doing the same thing three sentences later. "We are at war" has been used to justify the worst atrocities in human history.
EDIT: I’m also calling it whattaboutism because I don’t think folks are actually arguing that other nations should have entered the Iraq war on the side of Iraq or ISIS. If they’re legit arguing that, it’s valid (though I disagree).
