A lot of his speech, outside of cases where he's reading material written for him, is very much stream of consciousness. And he doesn't have much of that; he also has no focus and no discipline.
To be fair, this is why a lot of his base likes him. If you consider that his political base are generally less educated, less urban, and less sophisticated, then it makes sense to talk to them in plain language. Speaking articulately in complete sentences and paragraph structure appeals to what those folk dismiss as the "coastal elites" or the "liberal elites." But they simply don't want a President who sounds like college professor. Now whether an incoherent stream of semi-conciousness qualifies as the plain speech they're after is obviously still in question. But by differentiating himself in this way, he appeals to voters who don't what just more of the same elitist politicians. He comes across sounding like a "man of the people." Even though, of course, the rank and file American is the last person Donald Trump cares about.
He is just not qualified for any leadership role in so many ways...
Not at all. His behavior runs the gamut of anti-leadership qualities. He's had everything handed to him, and as a narcissist he believes he earned it all by his superior acumen. This leads him to treat underlings either as comparatively incompetent, or else as the cause of his failures. It's no wonder nearly all his original Cabinet has abandoned him. People think they can endure a problematic boss and just do their jobs. They cannot. And of course this is all spun as their own incompetence and stupidity; they just don't recognize the special genius that is Donald J. Trump.
So many people in the US don't just seem to realize the damage he's done to the country, especially internationally...
Americans not only have a broad streak of exceptionalism, it blends with a broad streak of individualism. Americans -- broadly painted, of course -- are so collectively narcissistic they (1) don't care what the rest of the world thinks of them, and (2) don't have much good to say, in most cases, about the rest of the world. As has been pointed out, Americans have been fed such a constant stream of indoctrination about how good they have it and how successful American capitalism is that they literally disregard any appearance of success or affluence in other countries. Many American's really don't care that the world views their country with derision, because they simply "know" they are still the best in the world and always will be.
I'm so very thankful to have lived outside the United States in many places for a considerable enough number of years both to see the U.S. from a different perspective, and to see why.
President Trump is both the epitome and the symptom of America's steady loss of prestige and power. The symptom, because this started long before the Trump Presidency. Although he has certainly accelerated it, it is by no means valid to lay it all at his feet, or even just to include the circle of enablers around him. This has been happening for many years, probably since the late 1980s or early 1990s. And the people responsible for it have been the increasingly blurry combination of U.S. big business and business-friendly politicians.
Donald Trump is the epitome of it because the U.S. is just doing what Donald Trump has done: play games with brand name recognition in order to squander and plunder it for the benefit of an otherwise indifferent elite. While the average American doesn't care what the rest of the world thinks about the country, I'm convinced that the average American business mogul or high-ranking politician (if there's even a difference anymore) doesn't care about anything idealist or institutional about any country. America, Russia, the United Kingdom -- they're all just the same. As long as there's a capitalist economic system, an exploitable labor force, and a pushover government, it's all just the same to them. "America" is a just a brand they're going to plunder until the resources are used up. Then they'll move on.
The difference, of course, is that the populations of other countries seem to catch this before it becomes a chronic problem and reign it in. But again, the marketing of the American Dream has been so wildly successful that we'll stand on the deck of the sinking ship with our hands over our hearts to the tune of "Stars and Stripes Forever" and listen to people tell us the water lapping around our ankles is just a socialist conspiracy theory.
Even in Canada, which had a good relationship with the country up to now, the majority of the people view the country with suspicion.
It's worth pointing out -- and Gillianren can correct my colonial history recollection, if needed -- but I believe Canada is one of the few countries that has beaten the U.S. militarily.
