Political relations between the United States, Spain, and Morocco appear to be entering a period of strategic reassessment as the confrontation with Iran intensifies and the war in the Middle East escalates.
As tensions grow between the government of Spanish Prime Minister Pedro Sánchez and US President Donald Trump over the war against Iran, questions are emerging about whether Washington could move some of its military operations from the Rota naval base in Spain’s Cádiz province to the Moroccan coast, a scenario that would represent one of the most complex and consequential shifts in the Mediterranean balance of power.
Statements by prominent US senator Lindsey Graham, alongside sharp criticism from President Trump directed at the Spanish government, have fueled speculation about such a possibility and triggered what observers describe as a deepening crisis of confidence between Madrid and Washington.
The debate intensified after the Spanish government reportedly reiterated its refusal to allow Rota base to be used as a launch point or logistical support hub for operations linked to the current war with Iran. Madrid has justified its position by citing the need to preserve national sovereignty and avoid direct involvement in a regional conflict.
This stance has created operational complications for Washington and sparked renewed debate among some US policymakers about the long-term viability of maintaining major American military facilities in Spain.
The US–Spain Defense Agreement
The bilateral defense agreement between Spain and the United States, signed in 1988 and later amended to regulate the American military presence in Spain, grants Madrid the authority to veto the types of military operations launched from its territory.
Some hawkish voices in Washington view this restriction as an unacceptable limitation during what they consider a wartime environment.
Currently, Rota Naval Base hosts around 6,000 US military personnel and their families and serves as a central hub for NATO’s Aegis ballistic missile defense system in Europe.
The American presence in Spain dates back to the 1953 Madrid Agreements, signed during the Cold War between the regime of Francisco Franco and the administration of US President Dwight D. Eisenhower. Under the deal, Spain received economic and military aid in exchange for allowing the United States to establish and operate several military bases, including Rota.
The agreement has been revised several times. The most recent updates included increasing the number of US Aegis-equipped destroyers stationed at Rota from four to six.
However, the revised arrangements also preserved Spanish sovereignty clauses under what Madrid calls the principle of “joint use.” These provisions have become a source of diplomatic friction during the Iran war, particularly after Spain refused to allow US aircraft to launch strikes against Tehran from bases on Spanish territory.
Spanish officials argue the war does not fall under NATO’s collective defense framework, does not serve Spain’s national defense interests, and lacks a UN mandate, positions that have angered parts of the US political establishment.
Ksar Sghir Base as a Strategic Alternative
Against this backdrop of tensions between Sánchez and Trump, discussion has resurfaced about Ksar Sghir naval base in northern Morocco, the fifth base of the Royal Moroccan Navy, as a potential alternative location capable of hosting American forces, naval vessels, helicopters, and military radar systems.
Technically, the base, inaugurated in 2010, occupies a highly strategic position along the Strait of Gibraltar. It is considered one of the most advanced facilities in the region, having been carved into rock formations and surrounded by terrain that offers strong natural protection against conventional missile attacks.
Located near the narrowest point of the strait, the base could also provide a powerful vantage point to monitor maritime traffic between the Atlantic Ocean and the Mediterranean Sea. Its position would allow US vessels to conduct logistical stops before entering or leaving the Mediterranean, potentially enhancing rapid deployment capabilities toward Africa and the Middle East.
Despite these advantages, one major obstacle remains for Washington: time and cost. Transforming Ksar Sghir into a facility comparable to Rota could require five to seven years of construction and investments estimated between $15 billion and $20 billion, particularly to expand military docks capable of accommodating aircraft carriers such as the Gerald R. Ford.
For the Moroccan base to function as a full command and control hub, it would also need to be integrated with US military satellite systems and the Aegis missile defense network, operated jointly with NATO. This would require extensive infrastructure development, including massive fuel storage facilities and maintenance workshops for advanced destroyers, factors that continue to complicate any immediate decision by Washington.
Strategic Implications of a US Presence in Ksar Sghir
Rota currently hosts four Arleigh Burke destroyers equipped with the Aegis system, along with a squadron of MH-60R Seahawk helicopters.
Relocating such assets to Morocco would effectively place a critical component of NATO’s missile defense architecture under the supervision of a strategic ally that does not impose sovereignty restrictions similar to those applied by Spain in the current Iran conflict.
Such a move could also significantly alter the regional balance of power by weakening Spain’s strategic leverage with Washington and NATO.
At the same time, it would elevate Morocco’s position among Washington’s key non-NATO allies, strengthening its role as a security pillar in Africa and the Mediterranean and potentially reinforcing its diplomatic standing on issues of territorial sovereignty.
For the United States, relocating the base could also provide greater operational flexibility outside the constraints of European political and bureaucratic frameworks.
For now, the evolution of the US-Spain dispute over strategic options remains a key factor in determining the future of American bases in Spain, including Rota, which has increasingly become part of the broader debate between Madrid and Washington as the Middle East war intensifies.
Amid this discussion, Morocco’s own position will ultimately depend on its national interests and the terms of any negotiations regarding the potential hosting of expanded US military facilities, a decision that would carry significant implications for the geopolitical dynamics of the Mediterranean and the Strait of Gibraltar.
