Since this opinion was expressed, that is, since mid-July, there have been significant changes in the US presidential election campaign: Biden refused to run again for this post on July 21, and US Vice President Kamala Harris became an official participant instead. Since then, Trump has lost a lot of popularity and Harris is now leading in most states. This is very unpleasant news for Russia, which hoped to weaken support for Ukraine with Trump's help to protect it from Russian occupiers.
Therefore, the Kremlin's hope for freezing the war, recognizing the occupied territories of Ukraine for Russia and easing sanctions is unlikely to happen. And in the issue of the war and its end, Ukraine will always have the last word, even if Trump becomes US president again. In addition, if the borders along the front line are frozen, will the Kremlin agree to lose part of the Kursk region, which has already been "liberated" by Ukraine? A very interesting question.
You are seeing things from a very narrow perspective since all your focus is on Ukraine and Ukraine alone.
If you expand your view, you can see things better.
US regime is already spread too thin around the world. They can not sustain this situation for long specially since
they are hemorrhaging money, in trillions. They need to reduce their costs at some point and that means abandoning some of the wars they are participating in specially when the problems pile on back home.
Also since according to all the National Security thing they release, China is on top of the lists of countries US has to declare war on, they will shift all their focus to East Asia sooner or later.
Remember that the conflict in Ukraine has been helping China grow which is not something the US regime wants. The Chinese have not only increased their economic relations with Russia (lots of money in it) they've also started receiving a lot more cheap Russian gas since the European markets were lost to Russia. On top of that the deindustrialization of Europe has also helped China grow significantly as the capital flees Europe.
So THIS is what the US regime cares about not what territory Russia annexed in Ukraine!
This also means the only difference the winner of the upcoming election in US would make is the approach and radicalism. As I pointed out in OP as well.
