I guess blindly following the advice of the military and intelligence community is actually an example of the worst they can do. Too many people in there who believe it is the role of America to be the police of the World. At least for Warren, has a weak track record on war and militarism.
So this is where I could prefer a more "small government" and libertarian-leaning candidate, at least to Warren assuming the worst as the question implies.
