The American Summit on Mutual Defense and Foreign Policy (commonly shortened to the Alamo Summit or the San Antonio Summit) was the fourth extraordinary summit of the Conference of American States, held in the city of San Antonio, Brazoria, from the 15th to the 20th of February in 2016. The summit was initially called for by Belize, Guatemala, Honduras, and El Salvador in late 2015, who all felt their national security was threatened by increasingly belligerent remarks from the bordering Mexican Social Republic, and on January 10th, 2016, the Federal Republic of Brazoria endorsed the call by the four Central American states and organized the summit after a review of security measures in place on its own border.
