Understanding presidential decisions for and against increased force in ongoing conflicts is a significant and important endeavor. The implications include the impact on future decisions to commit troops in the first place—such as in Syria. National security decision making also affects civil-military relations, as well as the balance between executive and congressional powers. Finally, as escalation and de-escalation involves either mission creep or the need to adjust policy aims by taking an appetite suppressant, understanding its dynamics will illuminate leader perceptions, the difference between wartime realities and prewar expectations, and the impact on the U.S. debt and the American public.
