The US military isn't that scary; the evidence to date is that it's ability to destroy counties ends somewhere around Iran's strength. The modelling I've seen is that any US-China war will take place in Asia and China will probably win it unless the US gets a lot of help (always possible). And the US has already been undermined by the likes of China, Russia and India and there isn't a lot they can do about it in the short term. They certainly don't have a military option to use against that grouping. At least not one that hasn't already been used in the case of Russia and failed to coerce them into cooperating.

The US military's "ability" is very contextual - for instance, the US could easily obliterate Iran with a MIRV or two, but for various geopolitical reasons they choose not to. Likewise, the US navy is of limited use against Iran due to the literal mountain range between their only coastline and the bulk of their landmass (and population), much of which is quite mountainous.
The US is the second largest manufacturing power, the largest economic power and the largest military power, but those things aren't even what makes it a scary threat.
There are things that make up the US that vastly increase its potential for self-organization when it is given an organizing principle. Yes, dynamism has taken a hit over the decades, but there are also a lot of aimless purposeless people right now that do have an appetite for purpose if given one.
Major modern countries today have red lines defined that they won't cross in order to keep the peace. Russia says don't attack Moscow or otherwise attempt to replace their government or they will nuke you. Nukes do change the structure of future wars between nuclear powers, which might actually make some aspects of it less extreme.
If Ukraine had nukes, they could have a red line like, "If you keep hitting hospitals and schools, we will nuke you. Powerplants and railroads we understand, but if you show us with your actions that you have no mercy for the weak and innocent, we will end you." Instead, they have nothing of the sort.
All the US has to do is wait for the enemy to make catastrophic moral failures and it's game over, because it rallies the people, the companies, the innovative talent, the allies, etc to reject it with force. It crystallizes the purpose.
We are energy independent and are advancing even more ways to expand the dimensions of that. You can't destroy our government, because we'll just recreate it.
We're forcing our allies to become more independent, because they got too soft and we need them hardened up. That only makes the US stronger, because strong allies are better for all of us. It makes us a better deterrent against war happening in the first place.
Meanwhile China is surrounded by countries that dislike it and don't trust it. Giving Canada and Mexico tough love is no comparison to the fundamental failures in the relationships China has with its neighbors in their region.
India is far more US aligned than with China, regardless of tensions. Neither North Korea nor Russia trust China, but they are forced to deal with it despite the buddy-buddy optics.
Failing to benefit from so many possible optimizations at the basic strategic level in their local region, any confidence in a favorable outcome for the CCP seems misplaced. Their failings probably cascade down into the other levels of preparation as well.
Military action is an extension of politics.
US politics do not support all out war against foreign nations at this point in time hence the half wars.
This goes for most first world nations.

Only if Geneva enters the equation.

What is India doing on this list?
Could China attack US? Why would US try to attack China in asia? Not an expert but that feels like losing proposition. I think people confuse proxy wars with wars. US is under no threat of being actually attacked.

With respect, Russia is being decimated (literally, at least the "big fortresses" that Russia has been gnawing at for months such as Pokrovsk have insane loss rates) by Ukraine's army who are mostly using donated shoddy Soviet-era remainders and decades old Western surplus.
If the US were to wage actual war with modern technology against either Russia or China (whose arms are based off of Soviet designs and stolen American plans), there is no chance in hell either would be able to do much against the US.
India is different but they're at least a democracy that's reasonably worth calling it that (despite Modi doing his best to dismantle it). I don't see any attempts of India to project power anywhere other than in its immediate neighborhood (i.e. the border disputes with Pakistan and China). They're no threat.
America doesn't and shouldn't fight China or Russia alone, so I don't know why we're talking about that.
Russia is basically on its way out as a military power. It can't even conquer Ukraine.
As for China, you don't fight China alone. What do you think military bases in Japan are for? Anyway, for the world's sake, China shouldn't start a war, but sometime you just can't stop stupid.
