Still, nobody would compare Churchill (or Bush; see above) to Hitler or Stalin. This is because Hitler was not just responsible for the people killed in WWII. Hitler and Stalin also killed people because they wanted to get rid of personal enemies and because they actually wanted to do some form of ethnic cleansing.
The US _today_ has the highest incarceration rate per 1000 people in the world. It uses slave labor in private prisons _today_. Why are you so keen on digging the Soviet past. Because it is safer to bark on a dead lion?
Well, the US government did ethnic cleansing during the WW2 by putting all Japanese americans to concentration camps. Don't bark onto dead lions. Look what your own government is doing with your own nation today. You have slave labour in private prisons!
