Trump and the Trump administration is constantly trying to prevent Ukraine from defending themselves and often helping Russia.
Just the fact that weapons bought for Ukraine by the alliance of the willing has an extra 10% tax on them is proof of that.
Trump has ended ALL economic aid to Ukraine, both military and civilian. And the administration is not enforcing the sanctions USA has against Russia.
There is no doubt that Trump refuses to help Ukraine, the only doubt can be in the motivation for it. Is he a Russian asset and a traitor? Or is it corruption because he hoped to make billions with Putin after the war? Or is it because he is an authoritarian moron?
My bet is on all 3.
