U.S. Secretary of State Marco Rubio’s four-day diplomatic tour from October 5 to October 8, 2026, focused on coordinating with NATO allies in Iceland, Greece, and Portugal to address regional security, energy, and rising tensions involving Russia and the Middle East. In Greece, Rubio’s visit included the 6th Greece-US Strategic Dialogue and a significant speech at the Pnyx in Athens. During this address, he asserted that the West was born in Athens, emphasizing a deep connection between ancient Greek civilization and the American republic. He urged European nations to bolster their defense, industry, and national sovereignty to navigate the coming decade. While Greek Foreign Minister Giorgos Gerapetritis welcomed the visit, opposition leader Rena Dourou criticized the government for failing to address the Cyprus issue. In his speech at the Pnyx, Rubio framed current global tensions as an inflection point for Western civilization, arguing that the United States and Europe must rediscover ancient virtues to confront modern dangers, including threats from Iran’s leadership. However, historian Touraj Daryaee challenged Rubio’s historical framing of the Greco-Persian Wars, describing it instead as a conflict between a massive world empire and various Greek city-states. Following his time in Greece, Rubio concluded his European tour in Lisbon, Portugal. Meeting with Prime Minister Luís Montenegro and Foreign Minister Paulo Rangel, Rubio discussed defense, economy, and technology. He emphasized the necessity for NATO allies to increase defense investment, noting that Portugal has met the 2% GDP target. Regarding the war in Ukraine, Rubio advocated for a negotiated solution and warned against military escalations that could expand the conflict into a larger regional war. The visit occurred amid local protests in Lisbon, where approximately 300 people demonstrated against U.S. foreign policy. ## Claims - Marco Rubio is leading the U.S. delegation for the 6th round of the U.S.-Greece Strategic Dialogue.
