Another example of how complex geopolitics can get

One can debate who is good and/or evil, and who is right and/or wrong. But I would remind folks that geopolitics is always messy. Even with the nazis and Japanese coming right out of central casting for ultimate bad guys, we must remember that the Allies were not always sainted. It would be easy to condemn Irish short-sightedness, etc., but please remember that these decisions were being made by people who had just fought the British in their own bloody war for (semi)independence, and already experienced there own atrocities, (look up any good history about the black & tans...). When one gets into the various captive peoples and nations under the Soviets, the world-wide colonies of France, Belgium, Holland, and Britain, etc. etc. - It gets complicated and not very 'black & white".
I would say, (as I've stated in the past), that almost all of these peoples were naive in their understanding or hopes for the outcome. Oh, I suppose the Irish might have been made mere captive peoples, (but still much worse than even a continuing British occupation would have been); but the various Slavic groups hoping for an end of oppression and murder from Stalin would have faced much worse under hitler, as would many of the Asian colonies hoping for better times through a Japanese win.  It gets complicated...
