Wasn’t there a Polish politician in the 30’s who, when asked why they wouldn’t allow soviet troops in Poland as part of an alliance against Hitler, said something like “with Germany we lose our wallets, with Russia we lose our soul?
The sentence sounds familiar, but I am not sure.
The track record is quite clear though. Estonia, Latvia and Lithuania accepted the Soviet troops and were all invaded by them. Finland delayed until eventually Soviets invaded anyway, but without their troops already present and against all odds the Finns won.
