Ukraine sagt

SS: President Volodymyr Zelenskiy said on Thursday Ukraine would not accept any bilateral agreement on its fate reached by Moscow and Washington without Kyiv’s involvement, and called for Europe to have a seat at the table in negotiations to end the war.The Ukrainian leader made the comments at a nuclear plant on his way to the Munich Security Conference, a day after U.S. President Donald Trump spoke to Russian leader Vladimir Putin Zelenskiy and announced the start of negotiations.

Yes they will..

The USA will drop all weapons support. Ukraine will cave immediately

Zelensky does not want to give up the impression that he’s weak. He/Ukraine will demand some exceedingly inconsequential concession and then claim that it was their idea while Russia/the USA won’t care
