Judging by his inauguration speech, he proposes to shrink American political influence at the same time as insisting on more international competition. A very Republican pair of goals even if it sounds weirdly like retreating from the world (and almost inherently contrary to being the shining light). But the whole thing is complicated by how clinically narcissistic he seems and how narrowly he seems personally to want to use power. I'm thinking, if we all got used to the US being the stable, responsible authority in the world, well that was then.
USA, a certain amount of ignominy is coming your way. Some good things might happen too but right now that's hopeful guesswork.
