The only "poles" in the world that matter are the decisive strategic nuclear arsenals, of which there are currently three that matter: the US, China, and Russia.
Nukes are only used for mutual destruction between equally weak militaries (ie. the ones you named), otherwise they are not of any use on the global scene. If they were, US military wouldn't have lost to cavemen in Afghanistan and Russia wouldn't have been stuck in the flat fields of Ukraine that has little to no natural defenses and China wouldn't have been attacking ships with a water gun...
Not to mention in the Modern Warfare era a small operation to take out the satellites would turn all 3 militaries and their nukes you mentioned into unarmed militias at best; specially United State's since almost all US weapons depend on satellites.

Well, if the USA was eliminated, as you seem to be pining for, then the destruction would no longer be
mutual, would it? The reason nukes haven't been used thus far is that there's a strategic balance between the US and the dictatorships of the world. If the USA is taken off the table, then nukes can and would be used because there would be no downside in doing so.
The US didn't "lose" to the fighters in Afghanistan, approximately 1% of our military capabilities lost to the fighters in Afghanistan. Had we bumped that up to even 2%, we would have annihilated that fighting force in the same way we annihilated the original Iraqi army. The US lost there because of political will (which, to be clear, I personally share), not because we don't have the technical capabilities to do so.
Begging for the end of the USA is the same as begging for continuous wars across the world. It's not fun like Red Dawn, it's really awful like The Last of Us.
Why end? When USSR fell apart, Russia didn't end. When US falls apart, America won't end either. America will still be a big country (maybe a couple of States declare independence) but a normal country not a rogue one.
The millisecond the US is no longer a unified military system--and thus can no longer provide a strategic counter-threat to Russia and China--the world will be at the mercy of these nuclear powers since they will have no deterrent in using the full force of their respective militaries.
As for "continuous wars", you seem to have forgotten a couple of facts.
First is that wars have always been part and parcel of our world and there is no escaping them. For thousands of years people have fought each other for a lot of reasons! and they are not about to stop, with or without USA.
Yes, for thousands of years that is true. For the last 70, even with the wars we've had, this has been the most peaceful in all of human history.
Again, you should really watch that streaming series, "The Last of Us" so see what you are asking for. The collapse of civilization is not fun. (And there sure as heck won't be anything resembling
Bitcoin in that world!

).
