Oh gosh, they are 'deeply troubled'.  Why can't people just tell Trump in the only language he understands.  "You have just made a decision that has the potential to destroy your real estate baubles in Manhattan, Scotland, and any other low lying place your name is emblazoned in gold letters."  

Forget the millions of people whose lives this decision threatens, including those in the US whose jobs are dependent on exports and the serious effects of climate change in the US, Trump doesn't give one dam- about any of that.  He would be perfectly fine with a historical attribution that makes his name garner more internet hits than any other human name even if it was totally and completely negative.
