There is no doubt that if USA wanted, they could double the EU aid Ukraine is receiving, and with that the war would be over much sooner. But with Trump as president, it is very unlikely that much aid will go to Ukraine.
How long it takes for Russia to finally collapse is hard to say, and Ukraine is definitely hurting too. But the advantage for Ukraine is that their economy is actually OK, because of the aid received from the coalition of the willing.
I have no hopes Trump will be removed, judging from how the Democrats behaved last time Trump was president. Wringing their hands on even investigating the accusations against Trump. Democrats are better than the Republicans, but that doesn't mean they are much good. Being better than the Republicans is a very low bar.
