Ah yes the comment was about the USSR, the picture was about China, that’s why I got confused. Though that now props the question whether they deliberately ignored the fact that the territory of the USSR grew past its 1930s borders in the aftermath of the war or not.

Also the “entire might of capitalism”? The USSR might have been fighting the entire might of fascism but got quite substantial help from a large part of the capitalist might

Which “most devastating invasion” are they even speaking about? WW2 showed no significant growth of china’s economy.
