Apparently, President-elect Donald Trump shoots from the hip and is emboldened by ignorance. From observing his behavior throughout years of campaigning and television performances, Trump's personality is no secret. Being brash and arrogant on a tv show, or being that way in his company, he is accountable only to him.
A sitting President has more responsibility and is expected to act with preparedness, armed with knowledge and facts about situations before acting. That is not his style.
Trump is a dangerous President because he exposes the nation to significant risk resulting from his temperament and deficient command of the facts before acting.
He attacked the Boeing Company with allegations about the high cost of two new presidential jets before he had the facts. Now, he is doing the same by attacking Lockheed Martin over the expense of the Joint Strike Fighter. It is not bad for a President to review high-cost profile programs. However, he is not yet sworn into office. He and his staff have not had the opportunity to study the situations. He is just "mouthing off."
He is also Tweeting to the Chinese about his opinions that do not yet change American policy. He may think that it is diplomatic negotiating, yet, his actions are premature and unprofessional. If he acts like a one-man band, he will mount a heap of trouble not just for himself, but for the nation. That is worrisome.
Add to that; he attacked the intelligence community.
Oh, and he is still at war with the Republican Party. Trump is a divider, not a uniter. It surely appears that he is leading with ignorance, and that is basically how the Chinese summed it up.
"Trump targets Lockheed Martin's F-35 fighter jet costs
Donald Trump on Monday criticized Lockheed Martin's F-35 fighter jet program as too expensive, the latest attack by the U.S. President-elect on large defense contractors."
