It was a main driver of the initial Cold War and conditioned on policy, basically neutering european sovereignty and pushing Soviet in a similar direction to try and counter this effort.

Political and economic dependency is a fallout that is still a problematic issue today, almost forty years after the fall of the USSR. The ongoing war in eastern Europe was pushed for by the US, more or less as a prolongation of the same strategy of US dominance in Europe.

If you can't recognize the 60+ years of relative peace that efforts like the Marshall Plan brought us, I don't know how you can recognize any time period in recorded history as being "peaceful".

If "relative peace" in the sense that a world war is actually going on is the most peaceful you can imagine, then I don't see much potential in having a conversation with you.
