And yes, you need an advantage between 4:1 to 10:1 in equipment to attack and hold a region, but this isn't everything.

Who cares about 20 times more in weapons when it's a question of time to see them transformed into a rusty pile of metal?
It's also starting to boil inside Russia, more and more people don't want to get poor and lose their sons MIA because of this war.
Victory?
I think it is still somewhat premature to talk about the victory of Russia. But even Gordon recently said that "to date, Ukraine has completely lost the Kherson region, partly the territory of the Kharkiv region, most of the territory of the Zaporozhye region, significant territories of the Donetsk and Luhansk regions. In this regard, to say that today we are something received, you can't. Of course, Putin received a lot".
Ukraine has no chance against Russia and never had. Even with general mobilization and unprecedented support from the West, Ukraine is losing to Russia's peacetime armies. If you think otherwise, stop taking hard drugs during daylight hours.
