If Trump has any common sense, or business sense, he will at least try to follow it, but the goals for the US are very hard to meet. If he doesn't, and it's business as usual, all of his Real Estate holdings in South Florida and Manhattan, now valued at over $2 billion, will soon be underwater and not worth 2 cents. It may not happen in Trump's lifetime, but in his children's and grandchildren's, costing them billions. See http://sealevel.climatecentral.org
