"...Latvia and Estonia have sided with Hitler during WWII.
They were the Bad Guys and they lost..."
They were demoted from independent countries to a part of the USSR during the negotiations of the pact between Hitler and Stalin and its secret additional protocol. Russia occupied both countries in 1939 - 2 years before Hitler declared war on Russia. This was against all international law. Poland was divided into a "Russian" and a "German" part in this sick treaty. Stalins problem was, that Hitler was a crazy moron that gave a sh** on treaties with so called "slavic subhuman beings" (as Hitler saw it) like Stalin. The "Fuehrer" wasn't exactly the guy that stood to a contract in good and bad days. Therefore Russia was -all of a sudden- attacked in 1941.
President Bush got it right: The Russians were (and are) good people, but Stalin was a real evil that played in the same horror league like Hitler did. We all can be more than happy, that things changed for good in Russia, but Russians have to work on the stalinistic past like other nations have to work on dark marks in their past.
