This map is complete fucking nonsense. It doesn't count the USA and UK liberating France and Belgium from the Nazis as an invasion, but it does count the USSR liberating all of eastern Europe from the Nazis as an invasion. Also the idea that colonised nations kicking out colonisers is an "invasion" is fuckin ridiculous. Portugal and Spain were not "invaded" by India and Morocco, they were kicked out from their colonies. Also Yugoslavia?
The person who made this should be shot in the head
