The Moscow military parade is meant to demonstrate the neo-imperial Russian military might, on the 80th anniversary of the USSR conquering half of Europe. That's the way it is presented, with slogans like «Можем повторить» i.e. “We can repeat it”.
The former striking the latter would be a bit like a terrorist accidentally blowing up on a bomb of their own making.
Is this a correct description of the end of WWII?
You could mention something about "Losing 80% of their population of fighting-age men and nearly losing their capital city to German aggression before turning the tide" and something about the race against the other Allies, but that is what happened.
Victory Day is basically the largest holiday in Russia.
They entered the Second World War as allies of Nazi Germany. When Germany inevitably turned on them, it was we—the collective West, with my own country playing a significant and costly role—who helped drag them out of the mess they’d enabled.
And yet, not long after, they turned on us. They occupied Eastern Europe, ruled it with an iron grip, and spent the next 80 years constructing a narrative in which they were the heroes—and that they’d done it all on their own.
Still, it's as correct to speak about the end of WWII in that terms as it is to describe love as four letter word.
The US nuked Japan post surrender (go look it up - the documents were declassified a decade ago) as a bluff to convince the Russians that they could not win a war where they attempted to take all of Europe.
As is, there was an attempted coup to overthrow the government due to the first (conditional) surrender.
Weird way to say defeating the Nazis despite millions in losses.
But they were fighting the brunt of the German military machine, and they did defeat them. It wasn't North Africa or Normandy that broke the Nazis, it was Russia.
