A lot of people, particularly in the UK are confused by Trump. I'm not.
I've travelled quite a lot in the USA, and met a lot of people who are not well educated, are not international business people, not trendy West or East Coast hipsters, and many of whom have never even left their home state.
A few years ago I visited someone I thought I knew quite well, in Indiana. Over dinner the converation led to President Obama. The vitriol spewed forth. they hated him, for all the reasons that we thought he was OK. One big issue was "why should anyone get healthcare for free when we have to pay?"
The protectionist "Born in The USA" "Stars & Stripes" "I'm alright Jack" approach is what got him into the White House, and it will keep him there. For him it's that all that counts. Everything he does it intended to enhance this image in the eyes of his voters. His voters, not the International community
The half wits and the deluded can protest till the cows come home. It will have no affect, it just makes them feel good, but what a waste of time money, and effort. Plus given Trumps unpredicability, it could well have been seriously counter productive. YES ! We showed him . . . . and lost any chance of some good trade agreements.
