Marco Rubio’s Lisbon Stop Highlights U.S.–Portugal Defense Ties and Legal Scrutiny of Lajes Air Base
By Drooid · · How we work
Core Event
U.S. Secretary of State Marco Rubio arrived in Lisbon on October 8 2026 for the final leg of a three-nation NATO tour that began in Reykjavík on October 5 2026. The visit focuses on deepening bilateral cooperation in defense, economic development, and technology, with particular attention to the strategic use of Lajes Air Base in the Azores for U.S. transit flights supporting operations in the Iran conflict.
Background & Context
Lajes Air Base has been used by the United States since World II under a 1951 Defense Agreement that permits peacetime transit without prior Portuguese approval. The base’s role expanded during the Cold War and now primarily provides refueling for trans-Atlantic flights. In the current Iran war, Portugal granted “conditional approval” for U.S. use of the base, a decision that contrasts with Spain’s refusal to host similar operations.
Portugal’s Prime Minister Luís Montenegro and Foreign Minister Paulo Rangel emphasized the long-standing security partnership, while opposition parties have questioned the legality of the authorization.
Data & Statistics
- Military personnel: Approximately 25,000 Portuguese troops (NATO).
- Defense spending: Just over 2 % of GDP; the government plans to raise this to around 3 % with dual-use civilian investments.
- U.S. presence: Lajes Air Base hosts a runway capable of handling heavy aircraft and serves as a key logistics hub for U.S. operations across the Atlantic.
- American community: More than 21,000 U.S. citizens reside in Portugal.
Official Statements & Responses
- Luís Montenegro stressed that “the United States is a partner and ally of Portugal in security and defense, since both countries are members of NATO and work together under the alliance every day.”
- Portuguese prosecutors opened an investigation, at the request of the Left Bloc party, into whether the Lajes authorization complies with domestic and international law.
Criticism & Opposition
- The Left Bloc filed a formal complaint alleging that the Lajes authorization may violate Portuguese law and international norms.
- The Portuguese Council for Peace and Cooperation (CPPC) organized protests in Lisbon on October 7 2026, condemning U.S. foreign policy and the planned visit.
- Government officials acknowledge the protests but say they will not affect the official program.
Conflicting Reports & Gaps
- Foreign Minister Rangel claims the base use is defensive and proportionate, while the Left Bloc and prosecutors question its legality, indicating a lack of consensus on whether the authorization meets international law standards.
- No public confirmation exists on whether Lajes will be a specific agenda item in Rubio’s meetings, leaving the extent of discussion uncertain.
Verbatim Quotes
- “Portugal is a great ally, very cooperative ally of the United States and a country with which we already have a solid and growing relationship. And we visit these countries in order to reinforce those ties,” — State Secretary Marco Rubio
- “When I was in Iceland on a regular basis, Russian aircraft or bombers or whatever would fly toward Iceland, do a loop of the island, and then fly back just to see how fast NATO planes would scramble,” — Robert Gerber
What’s Next
The State Department indicated that discussions in Lisbon will cover defense cooperation, economic development, and technology. Portuguese authorities have not disclosed a timetable for the investigation’s conclusions, and the outcome will likely influence future U.S. access to Lajes Air Base.
