Just what Europe doesn’t need at this time is a visit from Trump - what faux pas will he committed?

It's interesting that so many Trump supporters really don't like views about their President being expressed from outside the USA. (They don't like oppositional views from within either.) However, Trump himself has waded in immediately to comment and advise on Brexit and a leadership election within the Conservative Party. As long as he feels free to speak about that which he knows a little in another country, I suppose we should feel free to discuss things in his since apparently he is someone to be admired and his example followed.
