INTRODUCTION:
On December 26, 2004, a magnitude 9.0 earthquake struck off the west coast of the Banda Aceh region of Indonesia, percipitating a tremendous tsunami that devastated communities across Southeast Asia and the eastern coast of Africa. Populations were most affected in Indonesia, Sri Lanka, India, and Thailand, where over 175,000 people died and tens of thousands more went missing. A global humanitarian response was launched to relieve the suffering of the countless individuals whose families and homes lay in ruins. The United States government contributed a comprehensive force to the relief effort, involving multiple government agencies and a massive military presence to assist host nations with recovery and reconstruction initiatives. The success of the U.S. response largely resulted from the thorough integration and flexibility of the involved government organizations, which allowed for the development of ad hoc mechanisms within a broad strategic framework. The aftermath of the tsunami additionally demonstrated that the provision of relief assistance can be a key instrument of national power.

STRATEGY:
The inevitability of natural disasters demands formal response strategies to catastrophic events worldwide. To this end, regulations and protocols exist for the activation and deployment of various government agencies to provide humanitarian aid. However, because disasters differ greatly and require varying activities, what constitutes humanitarian assistance remains undefined and agencies are given flexibility and authority to devise aid mechanisms specific to each emergency. In the case of the Indian Ocean tsunami, the U.S. Agency for International Development (USAID), the Department of State, and the Department of Defense (DOD) adhered to standard strategies in deploying personnel and aid to the affected region. On the ground, relief workers acted in a tactically ad hoc manner but within broad strategic guidelines, addressing immediate issues in an integrated fashion.

INTEGRATED ELEMENTS OF NATIONAL POWER:
The established response mechanism effectively provided for the rapid deployment of humanitarian assistance. After U.S. Ambassadors and USAID initiated the response, other U.S. agencies, including the Department of Defense, the Department of Health and Human Services, and the Bureau for Land Management, soon joined the relief effort. The Defense Department deployed military and logistical assets in support of the USAID-led relief operations. U.S. embassies provided diplomatic coordination to ensure smooth cooperation among the multitude of governments involved. Agencies which collaborated in tsunami-affected areas exhibited great adaptability in order to achieve a common goal. USAID Disaster Assistance Response Teams on the ground received equipment and expertise from outside agencies, while ad hoc interagency task forces and working groups, such as the DOD-led Combined Support Force, were established to address disater-specific needs. In particular, USAID and DOD personnel cooperated throughout all organizational levels—from the field to strategic policy-making—in an effort to maximize coordination and streamline the U.S. response.

EVALUATION:
The successful implementation of the U.S. disaster relief effort was the result of established agency protocols, clear authority vested in USAID, organizational flexibility, strong interagency relationships fostered by past experiences, deference to expertise offered by a range of organizations, generous congressional support, and a shared mission. The few inefficiencies can be attributed to weak communication and information-sharing capabilities as well as differences in the organizational cultures of civilian and military actors.

RESULTS:
Inefficiencies in communications and coordination, while clearly impeding the effort, did not severely effect the overall success of the mission. The U.S. response helped mitigate loss of life, provide for communities’ basic needs, and initiate the rehabilitation and reconstruction phases of recovery. Additionally, the U.S. government, in demonstrating goodwill to the affected populations, improved its reputation among the largely Muslim areas of the region. This outcome benefitted U.S. national security objectives, especially in the context of the Global War on Terrorism.

CONCLUSION:
In response to the 2004 Indian Ocean tsunami, several U.S. government agencies united to accomplish a common goal: to save lives and provide basic services for affected populations. Leaders also sought to improve the U.S. image overseas by providing assistance and displaying the compassion of the American people. Successful interagency coordination materialized due to established protocols as well as flexible strategies that were created to deal with the specific effects and unique context of the disaster. Agency leaders, outside analysts, and members of Congress unanimously agree that U.S. government coordination was critical to the success of the tsunami relief effort.
