A very salient point.
One of the concerns I have is that a flippant remark by the Donald will get blown out of proportion, in fact the msm is trawling hard for just that. Hell, they're attacking things he didn't say!
In any case, Trump should identify policy and subject matter experts that will form his management team.
Every good leader needs an "A-team" of marshalls to accomplish goals. Trump being in front of that would make a lot of sense.
You are right. He could answer foreign policy questions with “I would speak in depth with Mr. Bolton before making a final decision” or something like that.
His foreign policy answers are a little weak and he needs to swallow some pride and get a “tutor” for current overseas events and how they came to be.
