For any unfamiliar with the history, Russia was a mass murdering machine in this era, vaporizing tens of millions of people, including Russians, in very short spans of time without even a second thought.
We all know Germans was. And some people would fling fecal allegations that “so was the US!”. No. German and Russian actions were categorically different than wartime casualties (even brutal, possibly criminal, wartime casualties like fire bombing heavily civilian enemy areas like Dresden)
You're right, America didn't intentionally engineer the death of millions until after the war, when it became the undisputed global superpower.
...If you choose to intentionally ignore slavery in the American South, Convict Leasing, and Jim Crow.

And in your living memory: Vietnam, Korea, the vile shit we did to Haiti and Chile, the 'Banana Republics', Iraq, Iran, Afghanistan, unconditionally supporting Israel and the Gulf States various war crimes and genocides, etc...
And of course, most recently, the sudden and complete excision of life-saving aid to children in Africa, leaving the world's most vulnerable to starve.
And also the total embargo on Cuba, to ensure starvation, with the intention of conquest, resource extraction, and collective punishment.
but God forbid someone on a message board tarnish the US's sterling reputation (relative to some of history's worst) during WWII.
