The difficulty and brutality of war were not new, and the U.S. military had long been developing a more professionalized attitude and wider view of strategy, as both Weigley and Millett et. al. attested. Still, Carson’s work showed an increasing focus on “modern science” as the answer to military problems, even on the battlefield. This was not just internal military theorizing, but an active engagement with the wider scientific community. This seemed to be a change of the previous military professionalism described by Weigley, which often looked at the military history of great leaders like Napoleon and its own academics like A. T. Mahan for development and guidance. Weigley and Bacevich might provide wider answers, as each saw an increase in military professional focus and reform after large-scale wars. Still, Weigley, Bacevich, and Millett et. al. all emphasized the difficulty of peacetime military preparedness and the American or widely democratic, issue that fear and emotionality drove preparedness and short-term bursts of military growth.
