I don't know what answer you expect. I think you didn't really miss options (broadly speaking), but your interpretation of each option is opinionated, and this is
extremely opinionated topic (obviously). So I wouldn't say you are wrong, you are just... opinionated.
1st one isn't really about "buying time". The prolongation of conflict is not a "side-effect" here, it's the whole point. And IMO it's a solid plan, honestly. If I was a citizen of the USA without any morals or inclinations to travel abroad, I would probably support it. This isn't a 100% solid plan, there are actually some questions if it works as it was supposed to work, but the incentive here seems blatantly obvious to me: war weakens Russia, weakens Europe, and nobody cares about Ukraine anyway, so by investing into the war carefully USA ends up winning, same as after WW1 and WW2. To me, the game plan is obvious here. It's just cynical, and that's why Biden (and other public-speaking supporters of the plan) would never say it as it is. No real politician would.
As to Europe wanting that... well, I would say it seems current EU leadership wants that, and I have pretty hard time explaining why, so I'll leave it aside. If you want some random data point: I, as a European citizen definitely don't want that. I don't doubt the majority of my fellow EU citizens would say they "support the support of Ukraine", but I don't find it surprising, given all media outlets chant 24/7 about how horrible Russia/Putin is.
I mean, yes, that's kinda saying "I think I know better than these guys", but I just don't see any benefits for the actual people (not governments) living in EU. This war hurts the economics, it hurts the relationships, and I personally have relatives in Ukraine, so I just want it to stop. I don't care on which terms, and obviously it cannot be the terms on which the war started. It's way too deep into the conflict and too many lives lost to call it a good outcome, but it's the best outcome.
So, not being a citizen of the USA, I am in favor of that alternative which is "as stupid as it sounds", the last one. I mostly have problems not with the option itself, but with the fact that for Trump to want it is not enough for it to happen. Because, as stated, a lot of people don't want this to happen, and it almost seems like Trump is mistaking being POTUS for being God. Meaning, the way he is doing things is stupidly blunt. It might work, it might escalate things more. In any case, having all of HN whining about how ashamed they are of their president is not a good start. And that product he helped BBC to make works awful for him and his plan.
