Well then, why did they occupy half of Europe for a number of decades? You know, that Warsaw Pact thingey?==
To counterbalance Nato which was created before Warsaw Pact. After one bloody war commies wanted to create defense against possible another.
At least that system plus nuclier weaponry kept peace in Europe for 50 years.
Oh, come on now. What, did the Kremlin invision something like Adenaur, Heath and Dulles, with their pens drawn as swords, attempting to succeed where Napoleon failed? Are you serious? NATO the hegemon - ooooh, ooooh, oooh! What bullies! What conquerors! /sarcasm
Wrong. It kept the whole world at war for fifty years with a nuclear EVIL EMPIRE, including repeated Soviet invasions of Eastern Europe to quell slave uprisings. We should have nuked the Soviet genocide machine out of existence before they ever got nukes. MAD was a liberal's dream - a no-win war.
