While it will get a lot more difficult without support from the US, I don't think that Ukraine has to give up now.
While the US is the biggest supporter so far with $84 billion, Europe has already supported Ukraine by $118 Billion, plus 74 Billions to be allocated, so more than double the US total amount.
And with North Korea actively intervening, I'm very sure support from South Korea will skyrocket soon with them finally sending weapons to Ukraine, which they so far refrained from. And that's without getting into non-EU countries support, like Canada or Australia for instance.
Maybe this will also wake up the EU from it's lethargy, though I fear the reasons may run deeper (like a lack of trained production workers and engineers to actually be able to increase production by much). At the very least, this will increase the moral support of Ukraine in most places - and with it, the pressure on the governments to do something for Ukraine.
