Humanitarian assistance and disaster relief

USSOUTHCOM's overseas humanitarian assistance and disaster relief programs build the capacity of host nations to respond to disasters and build their self-sufficiency while also empowering regional organizations. These programs provide valuable training to U.S. military units in responding effectively to assist the victims of storms, earthquakes, and other natural disasters through the provision of medical, surgical, dental, and veterinary services, as well as civil construction projects. The Humanitarian Assistance Program funds projects that enhance the capacity of host nations to respond when disasters strike and better prepare them to mitigate acts of terrorism. Humanitarian Assistance Program projects such as technical aid and the construction of disaster relief warehouses, emergency operation centers, shelters, and schools promote peace and stability, support the development of the civilian infrastructure necessary for economic and social reforms, and improve the living conditions of impoverished regions in the AOR. Humanitarian assistance exercises such as Exercise Nuevos Horizontes (New Horizons) involve the construction of schools, clinics, and water wells in countries throughout the region. At the same time, medical readiness exercises involving teams consisting of doctors, nurses and dentists also provide general and specialized health services to host nation citizens requiring care. These humanitarian assistance exercises, which last several months each, provide much-needed services and infrastructure, while providing critical training for deployed U.S. military forces. These exercises generally take place in rural, underprivileged areas. USSOUTHCOM attempts to combine these efforts with those of host-nation doctors, either military or civilian, to make them even more beneficial. In 2006, USSOUTHCOM sponsored 69 Medical Readiness Training Exercises in 15 nations, providing medical services to more than 270,000 citizens from the region. During 2007, USSOUTHCOM is scheduled to conduct 61 additional medical exercises in 14 partner nations. USSOUTHCOM sponsors disaster preparedness exercises, seminars and conferences to improve the collective ability of the U.S. and its partner nations to respond effectively and expeditiously to disasters. USSOUTHCOM has also supported the construction or improvement of three Emergency Operations Centers, 13 Disaster Relief Warehouses and prepositioned relief supplies across the region. Construction of eight additional Emergency Operation Centers and seven additional warehouses is ongoing. This type of multinational disaster preparedness has proven to increase the ability of USSOUTHCOM to work with America's partner nations. For example, following the 2005

of 1977 and the Treaty concerning the Permanent Neutrality and Operations of the Panama Canal), the U.S. Southern Command was relocated in Miami, Miami, Florida, on 26 September 1997. A new headquarters building was constructed and opened in 2010 adjacent to the old rented building in the Doral area of Miami-Dade County, Florida, Miami-Dade County. The complex features state-of-the-art planning and conference facilities. This capability is showcased in the 45,000-square-foot Conference Center of the Americas, which can support meetings of differing classification levels and multiple translations, information sources and video conferencing. In 2012, as many as a dozen SouthCom service members, together with a number of United States Secret Service, Secret Service officers, were disciplined after they were found to have brought prostitutes to their rooms shortly before President Obama arrived for a summit in Cartagena, Colombia. According to the Associated Press seven Army soldiers and two Marines received administrative punishments for what an official report cited by the wire service said was misconduct consisting "almost exclusively of patronizing prostitutes and adultery." Hiring prostitutes, the report added, "is a violation of the U.S. military code of justice." In 2014, SouthCom commander John F.

USSOUTHCOM's ''2017-2027 Theater Strategy'' states that potential challenges in the future include transregional and transnational threat networks (T3Ns) which include traditional criminal organizations, as well as the expanding potential of extremist organizations such as ISIL and Hezbollah operating in the region by taking advantage of weak Caribbean and Latin American institutions. USSOUTHCOM also notes that the region is "extremely vulnerable to natural disasters and the outbreak of infectious diseases" due to issues with governance and inequality. Finally, the report recognizes the growing presence of China, Iran and Russia in the region, and that the intentions of these nations bring "a challenge to every nation that values nonaggression, rule of law, and respect for human rights". These challenges have been used to promote relationships between the United States and other governments in the region.
