So Liam, the Good old US, came to Europe to protect us from communism ... that is very altruistic of you guys. Let me remind you that D-Day was launched earlier than planned because it was clear that the Russians were on their way to Berlin faster than expected. Had the Americans and Brits waited a bit longer, the cold war would have been totally different. Many decisions after D-Day were taken by the Allid high command in order to get to Berlin before the Russians to be able to dictate the settlement terms.
During WWII it was clear that 2 powers were emerging and that traditional European powers would decline forever. Having a USSR dominating all of Europe would have been a real problem for the US, so, appart from "saving" Europe's Butt, you, my friend, were taking care of your own butt, making sure to have Europe as a buffer zone. So please step down from the "World Saving" attitude.
