@liberty.post.daily: Marco Rubio switched into Spanish as the United States and Paraguay marked a new nuclear cooperation step. The secretary of state appeared beside Paraguayan officials for the signing of a memorandum focused on peaceful nuclear energy cooperation. U.S. and Paraguayan flags framed the event as Rubio addressed the room in Spanish and emphasized a closer relationship in the Americas. Energy partnerships can strengthen both regional security and economic ties when the terms stay transparent. Is this the kind of diplomacy Washington should expand? #MarcoRubio #paraguaya
