Not sure if this has been discussed on the boards
but…
it seems to me that it is possible
that President Trump has a list of things that countries "like" and a list of things they "do not like"
and uses these when negotiating.
For instance,
when Iran does not negotiate in fairness etc
President Trump declares the Golan Heights part of Israel
and moves the embassy to Jerusalem
When Israel deals unfairly
Palestine gets the hope of foreign aid
and the rebuilding of their country
and it's hard to take it back
when the decision is made.
So they better deal wisely and fairly
or they may discover what else is in that black bag of POTUS
