You (or you know, people who are historians who have studied this period through primary source documents) could say that the US and British not holding up the bargains made at Yalta by FDR also played a role… also, it couldn’t possibly be due to literal several centuries of western Europeans powers invading Russia making Russians paranoid? No… must but those crafty, despotic easterners…
Promises were made by BOTH sides at Yalta, and Churchill STILL gave that iron curtain speech… not imagining that Stalin was old and would die soon.
