The world knows that Trump is a total idiot, he's embarrassing to the USA, he says untrue things
The world "knows" no such thing. You are accepting biased reporting as the Gospel truth.
Many people actually thought Trump would change once he got elected. That was crazy. People are who they are. Trump is not now, nor has he ever been, "politically correct". That is one of his best attributes. He says what he means and he means what he says which is a completely novel attribute for an elected official. I certainly didn't want him to change into a lying politician like all our other elected officials. I would be happier if he toned it down once in a while so he wouldn't antagonize so many people though. You would have a much better understanding of Trump if you read The Art of War or the Prince. Starting with their advice to "keep your friends close and your enemies closer"
Trump has been amazingly successful in spite of the stonewalling by Congress (including the Republicans who hate him almost as much as the Democrats because he is a threat to them as well as he cleans the swamp) and never ending attacks from the left. If Trump exaggerates, IT's A LIE - there he goes AGAIN!!! If he makes a joke, they impeach him. Trump is not a politician but he made the same kind of promises other politician makes when running for office. He fulfilled many of the ones that were actually within his power to do so and tried for all of him. Quite novel for an elected official. Usually once they take office, they completely forget what made people vote for them. But, the ones like replacing Obama care were never within his power. He thought (silly him) that because the Republicans had been making that promise since the HCA was passed that he'd have their support. He didn't. Paul Ryan and Mitch McConnell made sure that didn't happen during the first two years while Republicans controlled both houses of Congress. Once the Republicans lost the house, it was never going to happen.
One of the things that most Americans don't understand is why medication is so expensive here in the US. One reason is that Congress (which is supposed to be working for the "people") passed a law that FORBIDS Medicare (the insurance plan for retirees) from negotiating drug prices and also forces Medicare to use third party administrators which increase the cost and suck off any "deals" made to reduce the price of the drugs by the manufacturer.. The result of that is that the US pays top dollar for drugs, the rest of the developed world like the UK and Europe get good deals, and the rest of the world gets drugs almost free. 60 minutes did a segment on this a few years ago and they presented the differential visually by using piles of pills. The US pile is 1 pill and the pile grows dramatically as you move your way around the world. France seems to be a really good negotiator
In addition to paying top dollar for the finished product, we also fund a lot of the research from tax dollars so we're paying on both ends. It's like the problem with the UN and NATO, we're the patsy for the world. Trump is finally standing up for us and I am actually happy to vote for him again in November. And to make matters worse, previous administrations encouraged the manufacturing of drugs to be off-shored, largely to China. If we have a headache, we have to depend on China to give us an aspirin. Trump is bringing drug production back to the US as well as the production of PPE. The Chinese really damaged us (deliberately) in the early days of the COVID epidemic by hiding the problem long enough for them to corner the market on the world's PPE supply. We had no reserves because the Obama administration - yep Joe Biden - actively decided to let our supply be depleted but not restored during their Swine Flu epidemic.
