I place more faith in some of the people that work for him that place the interests of the United States as a whole, above their personal legacy. A fairish deal that both sides hate, that will last long term is what is needed. One that completely fucks over the other side, might bring short term gain. However in the long run it could be problematic when you are out for blood and want payback. It is a balancing act between profit and long term planning.Spacker as Trump is even he would realise the starting point is the status quo. So no deal better than a bad deal would actually be the case.
Nobody likes a car salesmen when they find out they have been conned, and you will never go back to them again. I would rather keep you as a reliable partner for decades then burn that bridge for short term gain.
