While I would love for the Republicans to honor the wishes of its Republican base and cut aid to Ukraine and would like to be pleasantly surprised if they do, Professor Mearsheimer has correctly pointed out several times that the Republican Party doesn't listen to its base when it comes to foreign wars and the elites that are warhawks usually get their way.[https://www.youtube.com/watch?v=e7EOKBF1nbQ] The military/industrial complex and its lobbyists usually prevail despite the wishes.  Furthermore, Meaersheimer is highly skeptical that if Donald Trump were to win the war that he would end it quickly for various (See: [https://www.youtube.com/watch?v=e7EOKBF1nbQ Would Trump really pull out of Ukraine? With John Mearsheimer]). I also agree with Mearsheimer on this point.

If Donald Trump (or some other Republican) is elected in 2024, maybe Donald Trump (or that Republican) will surprise me and strike a peace agreement between Russia and Ukraine as early as 2024 or 2025 (Long-shot events do sometimes happen as evidenced by anyone who has ever seen a black swan). But even if such a thing were accomplished, things might blow up after another Democrat was elected.

Although I can potentially see the war in Ukraine ending in 2025 if Trump or another Republican is elected (Ukraine is not of vital national interest of the USA), it seems unlikely given the animosity between Russia/Ukraine now and other factors mentioned in the video [https://www.youtube.com/watch?v=rCLPxJ0wNhU INTERVIEW: John Mearsheimer On US Power & the Darkness Ahead for Ukraine]. But Trump did make relations between North Korea and the USA better for a while. However, regardless of when the war ends, it will have hurt Ukraine, Russia, the West and much of the world in significant ways and it would have been better if the war did not happen. For example, Ukraine is a big food producer and many third-world countries struggle when it comes to food security.

Mearsheimer believes that the war in Ukraine may end in a frozen conflict and that is the best we can hope for (See: [https://www.youtube.com/watch?v=FIfJNK2rLlQ Why Russia-Ukraine War May End In A Frozen Conflict & Why US Should Focus On China: John Mearsheimer]).

He also indicates that the frozen conflict will have flare up and I also agree with Mearsheimer on this point.
