He definitely puts the US above what is best for anyone else. As an American president that can be both a benefit and a curse. It is nice to finally have a president who cares more about the US than he does about globalism (like the past 5 presidents from both parties). He does however risk losing good will from most of the nations around. He definitely can be a bit of a bully.
I like having a President who stands up for what is good for America, but I frequently don't agree with how he does it.
It is interesting. Publicly he is loud, bombastic, aggressive, and a bully. From everyone I've heard, he is kind and helpful when dealt with one on one. That seems to be true for friends and opponents. I guess it goes back to him being a mixed bag.
Ironically, if he always showed his nice, generous side, I don't think he would've been elected.
