A brief stopover by five U.S. military helicopters in Costa Rica over the weekend drew the ire of lawmakers who claimed the landing violated Costa Rica's sovereignty. The executive and legislative branches of government have been disputing the legality of U.S. military vessels in Costa Rica since both countries signed a joint-patrol agreement in 1999.
Last August the Nicaraguan Army’s top official, Gen. Julio César Avilés, told reporters that the country’s military was in the process of buying airplanes, helicopters, and vessels to protect Nicaraguan sovereignty, “taking into account the evolution of threats and risks to our country.”
