The security guarantee is having Trump invested. Putin will be directly attacking Americans developing the land if he goes in. Just as he didn’t attack the embassy he won’t attack Americans. If he doesn’t do it Trump should let him fight the rest of the war on his own (or with France and the rest of Europe)
I think you’re right, and I think Ukraine is not thinking this through. See my post.
Trump could block Ukraine from using Elon’s Starlink internet terminals if Kiev doesn’t grant access to its critical mineral reserves. .....which have been widely used by Ukrainian troops on the battlefield.
And actually around half of Ukraines rare-earth deposits are “under Russian occupation”
