Central America Regional Security Initiative: Background and Policy Issues for Congress [December 17, 2015] [open pdf - 1MB]
"Central America faces significant security challenges. Criminal threats, fragile political and judicial systems, and social hardships such as poverty and unemployment contribute to widespread insecurity in the region. Consequently, improving security conditions in these countries is a difficult, multifaceted endeavor. Since U.S. drug demand contributes to regional security challenges and the consequences of citizen insecurity in Central America are potentially far-reaching--as demonstrated by the increasing number of migrants, asylum seekers, and refugees arriving at the U.S. border-the United States is collaborating with countries in the region to implement and refine security efforts."
