Nazi's, Hitler and WW2?

You cannot take Ribbentrop-Molotov agreement out of the context of the international European politics of the 20s and 30s. We can say there were roughly 4 groups of the international players: 1) Germany, Italy with a few sympathizing with them countries (Spain, Portugal, Hungary, Finland), 2) Britain and France, 3) Eastern European countries tied by international agreements with Britain, that is Czechoslovakia and Poland, 4) the Soviet Union. The expansionist intentions of Germany were not a secret. Hitler was extremely clear in his "Mein Kampf". That is why Britain and France conducted military consultations with the Soviet Union PRIOR to Munich agreement of 1938. MUNICH was the point that clearly showed to the Soviet Union the priorities chosen by Britain and France. Instead of containing Hitler they chose to push him to the East, in the direction of the USSR. The problem of Britain and France was who was more dangerous for them - "civilised Hitler" who just wanted some more land or "barbarian communist Stalin" with his ideology of the world revolution in his pocket. At some point they dicided that Hitler could help them to deal with Stalin. Stalin perfectly understood it. THAT IS WHY he concluded the agreement with Hitler. It was a shaky garantee for him to put off the war for some time. The stakes in that game were too high. Neither Britain with France nor the Soviet Union (let alone Germany) were extremely considerate about minor European countries. So, was Molotov-Ribbentrop agreement a cause for the WWII or it was a link of a whole chain? Answer it yourself now.
