From your lips...
The real powers that run our world sat Trump down and very clearly told him what they would permit him to do and what would not be permitted.
They gave him a certain latitude with regard to economics, trade deals, routing out violent gangs, etc. The non-negotiables were clearly delineated, under threat of Trump familial harm.
Their people are now firmly in place and run the White House. IMO, it is as simple as that.
