As Iraqi government forces struggle to hold their own against the self-declared Islamic State, the limitations of the current U.S. strategy have become clear. Our side is losing both individual battles and the larger war. Although the fight against the Islamic State will not be won by ground combat alone—Vietnam taught us too well the gap between tactical success and strategic victory—we must begin by winning on the battlefield. In turn, this will require a reexamination of how U.S. forces in the region operate, as well as what level of risk senior leaders are able to accept.
