New National Security Adviser.

President Trump surely knows from what pool to pick his National Security Advisers. Just in: General H.R. McMaster was appointed new National Security Adviser instead of recently resigned General Flynn. McMaster, apart from being a combat veteran, holds Ph.D. At this stage, apart from passing, again, this extremely important appointment over the head of a militant necocon John Bolton, Trump's propensity for choosing to this position US Armed Forces senior military officers looks very healthy. The reason for this is very simple: US "diplomacy", "academe" and spooks are so discredited by now that any alternative such as people who actually dealt all their lives with serious and very particular tasks is a good change. Moreover, US Armed Forces by now are probably the only organization left in US which is capable of sober and coherent assessment of the world outside and knows what is going on on the inside with American power. Consider this: US JCS and Russian Chief Of General Staff just met in Baku several days ago and the meeting was cordial and very substantive. This is what happens when, without being overly idealistic and overplaying the significance, real professionals begin to talk. In the end, this is how one deescalate things--militaries are simply better at that.

At this stage, placing non-spooks and other "deep state" operatives on such important positions is a right choice. I admit, I am being biased towards military people, but then again, I have a very good understanding of how normal military professionals, not some political appointees in epaulets, think. So, good choice, I think, at this stage. By this appointment President Trump really shows that he views US Armed Forces as a very important part of his political agenda. They are also his really serious insurance against any stupid moves by the (I am just following a fad here) "Deep State". This appointment boosts system's stability.  Not bad, not bad. 

UPDATE: greatly respected, albeit not always agreed to, by me Andrew J. Bacevich wrote today a wonderful review of General McMaster. Worth reading.
