You could watch some Perun videos on the subject. But THE question seems to be what victory looks like. Russia never was explicit on their objectives and what they would call a win.
Even if Ukraine would receive less help, Russia is not going to steamroll a country filled with people that know that losing to Russia means they will be starved, beaten and murdered.
I hope we don’t have to find out, but ita going to be a long and bloody road regardless of outcome.
