Why is all this celebrating taking place in Russia? Why no celebration here? Obama wishes we had lost the war?
Because this is the Russian Holiday that is celebrated and revered most. The Russians don't have an equivalent to the Forth of July. The Russians ceased celebrating May Day and November 7(The October Revolution) when the Soviet Union fell apart. They celebrated Unity Day (November 4) under the Romanovs and resumed celebrating it under the Russian Federation, but most Russians have a poor understanding of what the significance is. (Just so you, know, it commemorates the Russian people driving Polish invaders out of Moscow back in the early 1600's.)
In sum, The Day of Victory is it for the Russians. Americans have never celebrated V-E with equivalent vigor.
