On May 9, 2016, Russia marked the 71st anniversary of its Victory in the Great Patriotic War of 1941-1945 - that is, World War II. The war ended on the night of May 8, 1945, when the definitive Act of Military Surrender was signed in Berlin by representatives of the Nazi Supreme Command of the Armed Forces and the Allied Expeditionary Force, together with the Supreme High Command of the Soviet Red Army. Russia observes Victory Day on May 9 because the signing took place after midnight Moscow time.
For this year's celebrations, Russia's Aerospace Forces gave a show of military strength during the military parade in Moscow's Red Square, with Su-24 and Su-34 bombers, Su-25 attack planes, MiG-29 and Su-27 fighter aircraft, and other aircraft flying over the Red Square. The same day, Russian President Vladimir Putin hosted a reception at the Kremlin; at it, he stressed that the Soviet Union's "victory... a stern warning to all who would consider challenging us."
It is worth noting that Putin's remarks included no mention of the Allied forces, giving the impression that the Soviet Union had defeated Nazi Germany entirely on its own.
Following are excerpts of Putin's remarks at the Kremlin Victory Day reception:

"Our people accomplished the immortal feat of saving their homeland. We will always remember that it was the Soviet people that vanquished Nazism and achieved the grandiose and triumphant Victory. We know that a war turns into a patriotic war when people stand shoulder to shoulder in defense of their homeland. This was the case in that heroic and tragic year of 1941, when the Soviet Union's multi-ethnic people rose as one to fight the enemy...

We fought for our Motherland!' Let me raise a toast to the outstanding generation of victors! To Russia! To our Great Victory!"
