The scariest guy, Flynn, is gone. I did not like his obsession with Russia. Strange situation.
No one else "scares" me but there are a couple who are lacking in experience and competence. Betsy DeVos being the most obvioius.
However, Trump's national security team is shaping to be very strong, if they can keep the politics out. Like McMaster and Mattis a lot. I think John Kelly is going to be great, but he is tied down on this stupid immigration nonsense right now which is very unfortunate.
