I do not believe Trump (or anyone else) can fix the world.
However, people can make it worse than it otherwise would have been, which I think is true of Obama and would be true of Clinton as well.
I know it’s politics but saying you can fix the world is a bit much.
Throughout history, there have been serious challenges to the survival of civilization, both manmade and natural causes. It ALWAYS happens that when the mega-structures of civilization collapse, there are pockets of survival where remnants of the previous civilization and memories that carry down survive. The global mess cannot survive. But, what can be saved? Nations and local entities with resourceful people, determination, good leadership, and the resources to be self sufficient.
Trump with his initiatives can provide leadership and some turning around of things. There will then be areas that pull through the chaos which is inevitable.
First step....keep people in the countries where they are, and begin stabilization. Trump seems to get it, if you listen to his priorities.
I would be happy if he were to begin fixing the US. He can start by rescinding each and every one of Il Douchebag’s Executive Orders on the afternoon of the inauguration. The next day, begin the planning of the dissolution of the EPA, the departments of Energy and Education. Begin a detailed analysis of the budget and start cutting, using the US Constitution as the justification for a much, much, much smaller federal government.
