On May 8-9, millions of people around the world celebrate the Victory Day, commemorating the day Nazi Germany surrendered in 1945, ending WWII. The holiday is celebrated on May 8 in most parts of the world, and May 9 in the former Soviet states, due to time differences. This year marks the 71st anniversary of the end of the war, commonly considered to be the deadliest conflict in human history. An estimated 28,000,000 people were killed in the Soviet Union alone, making Victory Day an especially significant landmark in the Post-Soviet region.
