Military action should be the last resort. Gross build up makes it the first.

Before he became defense secretary, Gen. Jim Mattis once pleaded with Congress to invest more in State Department diplomacy.

Wow, Mattis appears to have his head screwed on right. In diplomacy military action is the last resort. All this emphasis on military build up makes war the first resort.  Naming Defense the War Department again would have a clarifying effect for the President, Congress and the public.
