You think that Russia's only way to move in a war is with nukes. But they still have a million reserve troops, all ready and waiting for Nato to make a wrong move.
Problem is those "troops" are only good at killing unarmed civilians. A++++ star grade for that. Top of excellence. The crème de la crème. Pride of Russia.
However, when challenged against a real army, with weapons, the wheels quickly fall off.
