There is one way in which it could make sense. If the US is able to extract economic benefits from Ukrainian territory, then it is likely to help Ukraine defend that territory in order to get those benefits.
Now whether those benefits are lucrative enough to warrant the US' help, I think not, which is why the deal apparently included no guarantees. The $500 billion is completely bullshit - they're not worth that much.
I would be extremely surprised if the other half of this profit fund was not eventually meant to go into Trump's pockets rather than to the United States itself.
