I'm still not sure whether Donald himself is just dumb or whether he knows he can get away with saying things because his voters are dumb. Neither option looks good in an international context...
Not only the Norway thing, but he also (pretends?) doesn't understand how NATO works. Being angry about NATO members, a defensive treaty, not joining an offensive campaign in Iran.
You cannot win US presidency twice while being dumb.

He has failed upward in an insane way. A combination of his petty exploitation of people's good nature and subordinates desperate to be trickled down upon have propelled him to a level of power and wealth he is not fit for outside of his greediness.
