That is unlikely to be true.

From day one this has been a NATO versus Russia war and it's objective was to keep Russia in a very LONG war that exhausts all their resources and weakens Russia as much as possible. Many US regime officials have said that they will "fight Russia to the last Ukrainian".
I don't see any reason or indication that this objective has changed. Not even slightly.

That means they will continue sending weapons to Ukraine, but only enough to keep them in this war not help them win or change the balance.

The shenanigans of Trump these days is not to halt weapon delivery or intelligence supply to Ukraine. But it is to first force Europeans to spend more so that he can decrease his expenses and second to put pressure on Ukraine to literally sell their country to the US regime (including the minerals deal that Zelensky was ordered to sign and he recently obeyed that order).
