Trump doesn't own those lands. They are owned by whoever won the dispute for them.
The Trump advantage is that he might be able to talk Putin into leaving some of the land for Ukraine in exchange for peace and some of the product of the land... rare earths.
The war-dead Ukrainians would be allowed to keep the land they are dead on. Their families would be allowed to return to work the 'mines' for both the US and Russia. The cost of losing.
Hopefully those Ukrainians who didn't fight, but fled the war, would be allowed to return to their family land, since Putin doesn't seem to want most of it. But they might be forced to mine the rare earths, as well.
Zelensky should be forced to do his work by the sweat of his back and brow, while other Ukrainians could use machinery.
