Peace in Europe from 1945 through the fall of the Soviet Order was achieved in Yalta

The meeting was a failure in many ways but it succeeded in creating the harsh realities that gave Europe peace for about fifty years, a peace that even outlived half its chief guarantors, the Warsaw Pact, a divided Germany, and the Soviet Union.

Yalta Conference

Recall that in the 20th Century peace in Europe, or anyway absence of general war in Europe, has meant simply no war of Germany and its allies against France and its allies.

Put another way, no war of allied central European nations versus allied peripheral European nations.

The solution was a new order of European alliances splitting Europe down the middle and, not occupying or disarming, but partitioning Germany outright, dividing it between the two opposed alliances.

In retrospect, Versailles failed because it was not draconian enough toward Germany.

The French at Versailles had that right, anyway.

Wilson was the worst fool there.

The current guarantors are NATO, the EU, and other pan-European institutions, all which include Germany and very nearly all of Europe except Russia.
