There will be no war. Uncle Sam already stated they're not going to support Taiwan.
One can only hope so because I don't think the global economy can endure the consequences of the US proxy war with China.
However, they've said this before too. With pretty much the same language too "We don't support independence" but then they sent Pelosi to Taiwan and increased weapons sale!
Translation: Sorry guys, we don't have enough money to support you. We gave away too much money and military aid to Ukraine and Israel so you're now on your own. Nothing personal, just business.
That's true but remember that they weren't bored in Washington one day that they decided to start this proxy war. They were seeking to contain China and significantly damage its economy and expansion. If they don't start that war, China will continue getting bigger. This proxy war is not something US can postpone!
Chances are, the Republicans are going to win in the US. Which means the war is going to stop (no chances for Ukraine without US support).
I don't think this is a Republican/Democrat thing, there are certain things that everyone in US regime agrees on. They may only have different approaches and in some details.
The NATO vs Russia thing is the same as NATO vs China thing. They have certain goals they won't stop without achieving some of them at least.
All wars end with a negotiation but for NATO (which is basically US dictating everything of it) to enter negotiation phase they have to have some advantage or have some wins on the battlefield. So far they have none otherwise they've been trying to get there. In fact the largely advertised "counter attack" months ago was supposed to be that "win" they needed. Ukraine was supposed to gain some ground defeating Russia in some fronts then they could start negotiating a truce and hope to stop the invasion by having some advantage over the Russians.
What can they do now though? What advantage does NATO have over Russia? The counter attack failed because Ukrainians listened to US/NATO and postponed it so much that Russia fortified its positions making any counter attack impossible.
And at the same time Russian advances is getting faster these days (some say at 2x the normal speed and it is winter). They can't negotiate anything with Russia at this point since they have nothing to bring to the negotiation table. Russia will demand a lot and the smallest one would be complete withdrawal of NATO from Russian borders. That term alone means they can't end the war with Russia regardless of who is the POTUS!
P.S. Don't be fooled by Trump's advertisement when he says "he will end the war if he wins". He was saying the same exact thing in his previous advertisement and about ending the war in Afghanistan and exiting there too if he won. Years later his own defense secretary colonel Miller said it was all bullshit
