> what was Neville Chamberlain's "peace in our time"?

To be fair, he is (now) widely derided for his policy of appeasement.

Also, the Molotov-Ribbentrop pact had the little caveat of partitioning Poland... To the benefit of both signatories. Not to mention the invasion of the Baltic states.

The attempted tripartite alliance between the UK, France, and the USSR would have also given up Eastern Poland to the Soviet Union. If the UK and France drew the line to Hitler's aggression in Poland, it would have been quite hypocritical to agree to give it to Stalin, instead.
