The US expelled the residents of the Bikini Atoll in 1946 to do atomic testing. The UK was expelling Chagossians until 1973.
So those actions make the Tatar (many Tatars collaborated with Nazi Germany in the Nazi invasion of the USSR) incident look like ancient history.
As is well documented with friendship agreements between Soviet Union and Nazi Germany, dividing future world into zones of influence, and of course Axis negotiations, USSR done as much.
Molotov-Ribbentrop pact was met with outrage even by Western communists and clearly tipped the situation such that Germany felt comfortable to continue, and indeed USSR started WWII on the side of the aggressor, jointly invading Poland.
Shall we continue this exchange of whataboutisms?
