Charles Krauthammer gave two main reasons why the selection of General H. R. McMaster to be national-security adviser was encouraging, and he also made another point about the language of Trump’s announcement:
What’s encouraging about him is the book that he wrote on Vietnam, and also he was the architect, one of the intellectual architects, of the surge in Iraq. In both instances he’s going against the prevailing assumptions and worldview. The surge we all now praise in retrospect — people were very skeptical of it, even within the Bush administration, in the military. It was kind of revolutionary, and he was there. So it tells you: This is a guy who will say what he thinks and promote what he wants. The other interesting element of the announcement was that the president went out of his to praise John Bolton, to say that even though he was one of the four candidates — he didn’t get the job — he said, “We want him in some other job in the White House.” It will be interesting to see what he gets.
