Think of how much we lost in two weeks because of one man.
Nations spent hundreds of thousands of dollars sending forces to Greenland. The US stock markets dipped because of the fear of World War 3. Infinite hours were wasted by politicians and officials all over the world, to plan new security strategies in a post NATO world.
All culminating with Trump basically saying "April fools! I was just kidding about Greenland."
I never expected to see such profound irresponsibility in my lifetime.
