Throughout the summer of 2010, Pakistan experienced severe flooding that overtook a large portion of the country, displacing millions of people, causing extensive physical damage, and resulting in significant economic losses. This case focuses on the role of the National Guard (and of the U.S. military, more broadly) in the international relief effort that unfolded alongside that of Pakistan’s government and military. In particular it highlights how various Guard and U.S. military assets that had been deployed to Afghanistan as part of the war there were reassigned to support the U.S.’s flood relief efforts in Pakistan, revealing the successes and challenges of transitioning from a war-footing to disaster response. In exploring how Guard leaders partnered with counterparts from other components of the U.S. government, Pakistani officials, and members of the international humanitarian community, the case also examines how they navigated a set of difficult civilian-military dynamics during a particularly tense period in U.S.-Pakistan relations.
