I think you described it very well already. And I'm sure you got your opinion already too.
The essence of your post could be: Trump is fascinating in a good and bad way. A Jekyll and Hyde in one person. Change within minutes possible. He's marvelous in playing the media and a dork in terms of diplomacy.
He disrupting the world's order and will shape the world in a direction his allies (does he have?) dislike and disagree. Even his enemies.
I believe in common sense. Common sense of American people who have take the burden of disruption. They have to pay the price, not the millionaires. They misuse Trump for their kleptomaniac business.
I reckon Trump will be POTUS not for the entire term when prices and inflation are rising high and also the interest rate. Economy will come to a downturn which will effect the whole world.
I would expect the head wind starting after the midterms. Maybe even earlier.
Trump will have to admit that his dreams will shatter.
