Apologies. I agree I post too long. Thank you for trusting my posts are with the best intentions, even the tongue in cheek / poke the bear ones
Not directed at you; There is a lot of talk about all Trump wants is the money (and siding with Putin) however there is another angle you could look at this IF you are open to different ideas / theories.
Trump is probably right that this war would not have started if he was in charge. The first bit started under Obama just after Obama's red lines on Syria proved to mean nothing. That sowed the seed. The second part happened under Biden.
Stay with me here

So if that is true

what would happen at the end of Trump's term? Putin would just reverse any deal and push on again?
So if the US has vested interests in Ukraine, and with that obviously their own people, and possibly forces in there with it, they would be there AFTER Trump's term finishes. So it could be more about ensuring that post Trump there is a deterrant from Putin moving back in. This talk of the EU stepping up is nonsense. They will still be standing back and shouting over the shoulders of those in front acting tough without doing anything but just maybe the above?
