Trump is way better than Obama.
The President is one man. He is surrounded by people who advise him, some being on his side and some being against him. We have already seen people more or less betray Trump.
The actions of Obama have set up all kinds of problems for America that won't be able to be straightened out for years. If there is war, it is not Trump's doing. Trump has simply been "stuck" in the position of taking care of a war that Obama set up to happen. If there is economic crash, Trump simply didn't have time to stop it when he was stuck in the driver's seat.
Many former presidents used the office of President for personal gain, and for gain for their cronies. Cleaning up the mess, and turning America around to be for the people, won't be easy. Here's what I mean via an example.
The IRS income tax is illegal for several reasons. The IRS is simply a private company, the Internal Revenue Service, even though it is written up in what looks like law. The tactics it uses is to threaten people and companies, taking them to court using tricks of law that people don't understand, is the only reason why the IRS wins in court.
Now, imagine that Trump decided to show people how to beat the IRS every time. What would happen to the economy if he did this? Probably 90% of the people would stop paying income tax, right? In the long run this would be a great thing for the country. In the short run it would probably be economic chaos. Why?
The legal and lawful places where Government can get tax money are export/import between the States, and between the USA and other nations. If there wasn't any income tax, Government would have to get its money from export/import tariffs. This would change the whole structure of international business. Suddenly, like over night, companies that moved out of the country would have to come back, or they just might lose everything because of extremely different taxes on export/imports.
The economic crash that followed the, above, two changes - big drop in IRS tax, and big increase in export/import tax - might be devastating. Yet, those two changes would make all kinds of things in America to be more legal and lawful.
So, how would Trump pull it off if he decided to do it? It would be a difficult thing to do and yet keep the economy from being harmed, and keep people and business from being harmed. Yet, it would be the right thing to do because it would take away a whole bunch of illegality and unlawfulness out of America.
In the long run, this simple thing would make America the strongest nation in the world, with all other nations formally bowing to her, and liking it that way. It would, also, take away the desire of a large percent of so-called American patriots to want to fight their Government.
Change is not easy. Cleaning up the mess of Obama and many Presidents before him will not be easy. It will look like Trump is doing all kinds of bad things for a while. But that's the only way he can make changes for the better in the mess we are in.
You have listed only promises Trump. Action and never will be. I refer to Trump as the host of the show "I am President". In addition to public relations and narcissism I see nothing else. If it is not confirmed that he is an agent of the Kremlin. Never before in America was not Secretary of state-a friend of Putin.
