I don't think many people, even on this board, appreciate just how much further ahead the United States is in terms of military technology and equipment than the rest of the world. Yes, it has been weakened by insane policy positions, grift and loss of personnel. There's no one who comes close in terms of force projection and sustainment, and that's the real key. Sure, China has a big army, but they're losing it to aging demographics on top of no ability to produce high-end components and materials locally. The Japanese have serious blue water navy capacity. The Koreans and Taiwan have been hardening and modernizing for decades. Just those three could easily handle China and North Korea. Yes, with significant losses, but they'd win. Nuclear is still a separate game altogether, and no one comes close to the first and second strike capacity of the US. It's always going to be lose-lose, though. Doesn't take many striking their target to ruin it for everyone.
I'd say more than 90% of Russian military hardware is Soviet era and their regulars are basically less trained than our Army National Guard. They have a handful of troops and toys that are on par with current elite and 5th generation capabilities. It's evident in Ukraine that Russia, a couple of hundred years later, is still throwing bodies at the enemy as their de facto strategy. Europe and the United States have been planning on fielding current military hardware and training Ukrainian force to at least a basic proficiency on it for a year. Russia has ramped up domestic production of ammunition and will be completing their second mobilization around the same time.
I guess in the next several months we get to finally see if the theory that quality can overcome quantity works or not. It's not going to make a difference globally, though it (along with the suicidal policies in the West that spring forth from Davos) will hasten the inevitable collapse of the American era of free global trade.
