Trump’s “plan” is too choose whatever is best for him psychotically and amorally. He’s not where he is right now because he had a plan, but because as you put it, the path was laid for him. It became clear with the drastic changes and statements he began his administration with. A destination was presented to him, and he’s tried to follow the path to it with the indications he has been given. Sometimes, he has even blurted out the “landmarks” prematurely, like his comments on Greenland and Canada.

He’s just at a point he realizes he can already exploit, which probably seems like a good option to him since some of the directions he has received aren’t working out that well for him.
