Trump befor the elections and Trump after are two different man. After he won the elections, he began to speak not that it is necessary to speak, but that he really is thinking, and it sems that sometimes it's wery difficult to him. Seems, that sometimes he is forgetting, that he is leading not only the toy soldiers game, but a huge country with hundreds millios of man and with an enfluence on a whole world. His half idiotic ambitions and a white house... years ago only comic movies could imagine it.
Trump a businesman and Trump a politican are also two big differences. Then you do busines, there are both parth interested in a dela, or not interested and there is no deal at the result. But when he became a president, all other countries can not simply shut the door, when he says something stupid aln walk away, they have to deal with him anyhow, agry or not agry, but the negotiations must be anyhow.
From the other side, Trump is a person without complexes and a strong leader at the same time. America was missing a strong leader for a long long period of time, from Clinton's time, and the positive changes are have been expected very and very much. Strong hand in economic, imigration, fight against the terrorists and so long. But not to the prejudice of other things
