I don' have a problem if he gets along well with Putin or Erdogan, or Castro. I'm convinced that he will be a lot more respected by most world leaders than Obama has been and that will make a big difference for world peace. ISIS will probably start wetting their pants in January. The Muslim Brotherhood in Egypt are already worried.
The main problem we will have in Europe is that when ISIS gets defeated, most of them will run like rats back to Europe where they will be welcomed with open arms by our stupid politicians. Europe's future is in deep trouble. It will be safer to go to Guatemala, El Salvador, Caracas, Soweto or the favelas of Rio than to visit Paris, London, Rome, Berlin or Malmo, to name a few EU cities.
