Yes, it seems impossible to try to guess what he will do? But even without US aid, Ukraine will still receive much aid from other countries, and Ukraine's economy is doing much much better than Russia. 15 days to go before Trump is inaugurated.

If I had to make a guess, it seems like Putin isn't willing to negotiate, and it might be Trump's best bet to continue or even increase aid to Ukraine to save face, when it turns out peace negotiations are going nowhere.

But that's probably just me trying to rationalize what I hope for.
