I'm struggling to see the problem, Trump gave a wishy washy answer, because of course he wanted Putin to go, and if Putin went, Trump would have jumped in an F14 and got there. Trump cant go if putin isnt going, because he reads that if he shows an empty chair, that putins nose will be put out for any future meeting.
So he made a delicate balance. He is trying to dance with Putin.
Take the win, a meeting took place, maybe it leads to the next meeting. Maybe it doesnt, once the result of this meeting is clear, we will see either nice trump -lets have another meeting. Or nasty trump, threatens US sanctions on anyone buying russian oil/gas. 200% tarriff on all their exports to USA, and 5 more F16 and 100 abrams for Ukraine. Then a week later he will ask if anyone wants a next meeting.
