It depends whether you believe the paper strength or actual strength. On paper the Russian army was the second most powerful in the world. In practice it's the second most powerful in Ukraine. On paper the US army is the most powerful in the world. In practice they've been brought to a standstill by a third-rate power in the middle east. Before that in Vietnam, Iraq, and by something that's barely a country, Afghanistan. Some years ago I saw a Vietnamese film about the American War in which an NVA officer told his men "kill them and keep killing them until they stop coming". It doesn't matter how many expensive toys you have if the other side is determined to outlast you. And don't forget who makes up NATO. Would you want to go up against someone like the Finns? Ask any US troops who have trained with them.
