Trump is ignorant and that is a dangerous person to have anywhere near the levers of power. This is especially true given Trump's propensity to fly off the handle, to potentially turn a dispute over airspace into a nuclear confrontation.
We cannot elect a man who has no context for decision-making. He may know business (although that's questionable to me), but he has no idea of history, has never read a presidential biography, and changes his positions on a dime.
#NeverTrump. Ever.
