Those are valid concerns and I can see what you are saying. I also am not wild about Steve Bannon being part of the Trump team. I would add to your list above the fact that Trump doesn't appear very interested in intelligence briefings, which would indicate he's not really taking the job of being president very seriously. In fact it would appear that he's ok with Pence doing the day to day stuff, and Trump will just sit back and make decisions when called upon. Kind of like how he runs his businesses, I would guess.
It also appears like he isn't going to sit back and allow China to get away with all of the blatant corporate theft and bullying anymore either. The Chinese are pretty cheesed right now with Trump's Taiwan statements, and maybe its time they were served notice that there's a new sheriff in town, that isn't going to just let China push everyone around. Trade with China has been so completely one-sided and something has to give somewhere. It will be interesting to see how that dynamic plays out.
That all being said, Trump's victory is unprecedented. Never before, has someone like this been elected. It's going to take time to figure things out. I am cautiously optimistic, only because up until now everyone, and I mean everyone, has totally underestimated Trump at every turn. And he's somehow made them all look foolish. I am hopeful he is going to do that again.
