Because Trump really is a bumbling “idiot/moron:”
Trump issued the directive earlier this year to H.R. McMaster...
McMaster directed his staff at the National Security Council to prepare a presidential memorandum ordering military dependents in South Korea to leave the country. Within a day, the memorandum made its way to chief of staff John Kelly's office.
"It was an order. It wasn't, 'I'm thinking about it,'" one senior administration official said of Trump's directive. "We saw it as a done deal."
…
Behind the scenes, Defense Secretary James Mattis and Kelly devised a compromise, according to two administration officials, and convinced the President to agree to a scaled-down directive that would bar military personnel in South Korea from bringing their families there during future tours, but avoid a dramatic evacuation, a senior administration official said. A new memorandum was drafted, but it too was never implemented.
They actually are babysitting him. It’s hard to imagine the military letting Trump start a war with North Korea given the adult daycare scenario in leaked accounts like this… which show North Korea what’s going on over here.
None of this makes us safer.
