Most of those tanks where outdated shit from the 60s. Their only propose was to be stockpiled for russiaboos to jerk themselves off. Anyway, drones have reshaped tactics so much that i doubt that those tanks would be usefull for anything today.
Militarily russia is disastrous, but they still hold a few cards. They do have a nuclear arsenal and they really want us to believe that they are stupid enough to use them in case of need. They have a solid net of spies, mostly around ex USSR countries and they pretty much found the way to weaponize our ellections. Also... they dont have any problem rising slave armies and throwing them at us...
What about russian allies? China and India? I dont see them fighting with russia at the cost of what that could mean for their economies... but what if?
And in our side, our governments are fragile and slow to react and... maybe im wrong in this one cause, while being part of the west, im pretty god damn far from the frontline, but i feel that in general we really don't want to fight.
Part them in pieces and take the propaganda away and they will slowly reeducate themselves.. most countries that where in the russian sphere arent very fonded of russia today. The problem isn't russia per se but the power they have.
Are you in the front? Ukraine is really using maxim guns?
