I disagree with your position, Ukraine is half way around the world and is a European problem, the US has no business being involved
President Trump will soon end the conflict in Ukraine, a war that was started by the Obama administration in Feb 2014 and its been continuing ever since
Russia isn't the world enemy #1 communist China is, and president Trump will work on stopping the Dragon soon!
Your opinion is shared by about half of America. Most want to do something though.
Wide partisan divisions remain in Americans’ views of the war in Ukraine To most it is a partisan issue but that is not my case. I just happen to like nations that have the consent of the governed and dislike those that do not. The same for stuff like freedom of speech and religion, which is promoted more in Ukraine than in Russia. I also think that America has some obligations to help those aligned with her values and oppose those that do not. This includes helping prosecute those charged with war crimes.
There Must Be a Reckoning for Russian War Crimes
Since China and Russia are pretty much allies, you see no problem with China providing war supplies, giving some aid to Russia and voicing basically "no limits" to their cooperation?
China and Russia: A New Cold War? Yes, China voices neutrality but is it? (meanwhile a Chinese vessel, with a Russia captain drags its anchor to sever cables in Europe).
Our views likely differ on what USA exceptionalism is and how aiding Ukraine fits into that. Our thoughts too differ on what the results of isolationism will be if the USA pulls out. Remember even a small slip from a NATO member will require the USA to defend. If isolationism is the answer what will be the outcome? Will it embolden Russia and others in the future? I asked an ai and got this as a conclusion.
"Conclusion:
Ultimately, whether U.S. isolationism would harm or help end the war in Ukraine is complex. While it could lead to immediate benefits in terms of avoiding military entanglements, it might also significantly weaken Ukraine’s position and embolden aggressive actions by Russia. A thorough analysis of the situation, including the views of international stakeholders, would be necessary to gauge the full impact of such a shift."
Anyway, I respect your and all opinions on this matter and if the USA stops aid, I guess we will see how that works out or even better Trump will end the war entirely and everyone will reach a deal.
