Most Canadians miss an important issue: these parades are not cheap and Russia is not a very wealthy country. The amount of money spent each year in Moscow just on avoiding the rain during the parades was an internet joke for many years now. Most Russians would prefer these money spent on social payments instead of parade, but, unfortunately, noone believes in Russian government anymore. You know that Russia spent very little on social payments during COVID despite almost no government debt and huge positive balance in the "Russian national wealth fund and Russian reserve fund". In fact, they even start to increase them recently. But make no mistakes: these funds will never be used to benefit the citizens, it will only be used to pay Putin's friends.
P.S.: there is no reason to talk about what happened 80 years ago: what is happening now is more important. Unfortunately, the internal politics of Russian government is to talk about WW2, not about its economical, political, and freedom problems. Just keep in mind: if you talk about Russia and discuss WW2 instead of current situation - you play their game. If you want to talk about Russia - talk about Navany, Navalny's fund, Ukraine, poisoning, Russian money abroad. This is what is important. WW2 ended 76 years ago and talk about it is just a diversion from the crimes that Putin is committing now.
