Dien' Pobiedy:
Today is when Russians celebrate (at least they celebrated it under the Soviets, but I'm sure they still celebrate it now) Dien' Pobiedy, or Victory Day, the victory of course being victory over the Nazis (or, as the Russians say, Fascists). Americans mark V-E day on May 8, but I take it that the surrender on the Russian front happened on the 9th.
Here are some pictures

Stalin, however, thought that the USSR was not represented by a high enough ranking representative at the May 7 ceremony, and so forced the Germans to sign another surrender document at the Soviet HQ in Berlin on May 9. The May 9 ceremony had no legal significance (because the Germans had already surrendered anyway), but did give Stalin an opportunity to accentuate his role in the victory.
I wonder: Is the 48-star U.S. flag the one on display?
I was in St. Petersburg for Dien' Pobedy 1997. What a wonderful experience.
To TC: I was in Warsaw exactly a year ago, the biggest of those V-days. The whole country was in turmoil over Putin's remarks not mentioning its contributions to victory, while mentioning a relatively layabout France. The Bolshoi, in town on a tour, was boycotted, and President Kwasniewski kicked around for going to Moscow. Few noticed, however, that two days earlier Putin had called the break up of the Soviet Union "the greatest tragedy of the XXth century" (just think what else happened in that century).
