trump seems to do this out of habit when negotiating anything.
First he makes a complete mess of things on purpose, to make everyone squirm, knowing that he will eventually except the deal. It is his way of showing everyone how broken things are before he swoops in to agree to something that fixes the situation.
Right now is the broken/squirmy part.
Wait another week or two, I think trump is waiting for the EU to come together to announce that they will be taking over the responsibility of financing and possibly EU boots in Ukraine, No US boots & US still gets mineral rights.
trump will wait to see if the EU will unite the clans.
If the EU does agree to lead, then trump will back the agreement, uniting the EU, patching up the EU and the US relations unifying EU & US v. Russia.
Well trump takes responsibility for unifying the alliance, saving Ukraine, getting minerals for the US all well he gets Ukraine off of his back well he can concern himself with other matters.
