I don't follow your logic here.
Someone might think that, if the enemy only has enough weapons to kill of half of your country rather than all of it, that sacrificing that half might be worth the risk of launching. There's a lower point at which 'enough' becomes 'not enough' deterrent before you get to full disarmament.
We have to give them a chance.
No, we don't, we have to judge them based on their previous actions. Trump demonstrably couldn't give a shit what happens to Ukraine, and actively wants to bail Putin out of the shitshow that he's started. Putin has a demonstrable history of talking peace for a few years and then invading someone else. If Trump doesn't want any part of peacekeeping or mutual defence, he needs to butt the fuck out of negotiations, take his toys and go back home. Putin needs to be put in a tightly controlled, tightly monitored treaty where there are real penalties for even thinking about breaching the terms.
Not going to happen though. You forgot about their submarines, for a start.
Russia's navy is even more of a joke than their land forces, which have performed abysmally. Nobody is worried about Russian subs at the moment.
While Russia put up with it, expanding the nuclear umbrella closer to Russia has indeed led to deteriorating East-West relations.
Again, nobody's talking about putting anything nuclear in Ukraine, but even if they were that's not any closer to Russia than they are now. East-West relations have deteriorated because Putin keeps invading places, and the excuses he keeps giving are 'but we're under attack' - nobody's attacking Russia, nobody wants it.
So what is it about Ukraine that make Russia so averse to it joining NATO?
Some of it is the food and mineral supplies that the corrupt oligarchy want to share out between them, which might for a short while plug the huge holes in the Russian economy. Part of it is that it's the only real avenue for expansion back into Europe for Putin's imperialist ambitions. A third part is securing the land corridor to the warm-water port he's established by annexing Crimea.
Crimea perhaps? That if Ukraine tried to recapture it, it would have NATO backing? Putin has mentioned this.
It's going to be a key component of the peace negotiations when they really start - Ukraine are going to want it back, but Russia aren't going to want to let it go. If Russia keep it, but don't get a land corridor, the whole thing is just being set up for another invasion in a few years time. If Ukraine gets it back, Russia are going to be itching for another go, Europe will have to put considerable thought into how they're going to help protect it in the future.
In four years time, when Trump's been booted, perhaps someone with some sense will get into the White House, and Ukrainian acceptance into NATO will be viable again - or, earlier than that, if Trump decides he's had enough of NATO and convinces enough of Congress to withdraw from it.
