At the outset of some of the most impactful wars in history, policymakers have assumed that the duration of conflict would be brief. Unfortunately, their assumptions were often wrong, as may wars like those in Vietnam, Iraq, and Afghanistan only grew more complicated with the passage of time. However, at least in these three cases, the reality of prolonged stalemate did not stop policymakers from setting withdrawal deadlines to assuage public anxieties and improve military performance. The pressures contributing to these consistent decisions across time are still relevant now. Therefore, as the United States currently seeks to deter great-power rivals and rogue regimes while combating terrorism, it is as important as ever to understand the roles and potential outcomes of withdrawal deadlines in war.
In this new Atlantic Council report, Withdrawal Deadlines In War: Vietnam, Iraq, and Afghanistan, Dr. Paul D. Miller examines the effect of withdrawal timetables on public opinion, military success, and policymakers’ goals across the three titular case studies. He finds that “Withdrawal timelines do not achieve the political benefits that policymakers desire, but they do incur the risks policymakers rightly fear.” In the face of prolonged and difficult military challenges, withdrawal deadlines can exacerbate outcomes at crucial moments, and thus policymakers must tread carefully.
