“The morality of U.S. conduct of the war was a major political issue both in the United States and abroad. First, there was the question whether a proxy war…without a clear and decisive path to victory was worth fighting and worth the casualties sustained both by the combatants and by civilians. Second, there was the question whether a guerrilla war in which the enemy was often indistinguishable from civilians could be fought at all without unacceptable casualties among innocent civilians. Last, there was the question whether young, inexperienced U.S. soldiers — many of them involuntary conscripts — could reasonably be expected to engage in such guerrilla warfare without succumbing to stress and resorting to acts of wanton brutality. Fighting a mostly invisible enemy mixed in the civilian population — an enemy that did not obey the conventional rules of warfare — and suffering injuries and deaths from booby traps and attacks by soldiers who pretended to be civilians could not help but lead to the kind of fear and hatred that would compromise morals.”
