I think the proof of his past tendencies show Trump even tries to contrive personal advantage where none exists, outside of his fantasies. Of course he would suck every milligram of (even imaginary) credit from any situation.
Proof in point: the stock market takes a record pounding (from the fallout of his growing failure to manage a real crisis - not of his own creation) and quickly posts an image of his signature across a page of stock results the only day they didn’t drop that week.
The traditional term for this is demagoguery. The method is despotic. Nero.
