I don't think we're going to agree on that one. Poland was desperately trying to avoid being crushed by either Germany or Russia at that point and tried to save its own hide at the expense of Czechoslovakia. It's not as though Poland would have invaded Czechoslovakia itself, the way Germany and Russia made their pact.
Not quite idential.
Incidentally, I was in Prague 2 days ago, what a beautiful city it is.
Right, we then have to agree to disagree. The domestic excuse for Molotov-Ribbentrop pact in USSR was also, to recite my schoolbook, "an attempt to postpone inevitable war with Nazi Germany", politicians don't really have much imagination anywhere. Poland's role in Czechoslovakia was marginal, however military contribution of USSR in Polish campaign was also insignificant. To me it's almost as if Hitler used cookie-cutter strategy both times, and both adversaries fell for it.
Never been to Czech yet, but I've spent three fine days in Krakow last month. Beautiful town, fortunately left mostly intact in the war.
