Cuban Foreign Minister Opposes Blockade at U.N. Cuban Foreign Minister Bruno Rodriguez stood up to U.S. Ambassador Mike Waltz at the U.N. General Assembly on Tuesday, in a confrontation that revealed the deepening hostility surrounding Washington's escalating war of economic aggression on the island. While Waltz spoke in the chamber against the annual resolution condemning the American embargo, Rodriguez approached the podium and demanded a point of settlement, calling the ambassador a "liar." Waltz yelled back: "Do you understand who you're dealing with? This is America. Backing up, you can't silence me." The meeting was stopped for a short time. Rodriguez responded at X that Waltz was at the United Nations, "not at a national security meeting at the White House," and accused Washington of "gross lies" to justify its "criminal energy blockade."
