Rubio seeks G7 backing for Iran war as European allies resist involvement

U.S. Secretary of State Marco Rubio met with foreign ministers from Britain, France, Germany, Italy, Japan, Canada, and the European Union in France on March 27 to rally support for the Trump administration's military campaign against Iran. The meeting aimed to bridge a widening divide between Washington and its Western allies, who said they were not informed of U.S. plans beforehand and expressed reluctance to enter what could become a prolonged conflict. European leaders, including Germany's defense minister, criticized the lack of an exit strategy, while the EU's foreign policy chief emphasized the need for de-escalation as the war's consequences spread globally. Rubio argued that allies should contribute to reopening the Strait of Hormuz, a vital waterway blocked by Iran, and later suggested the U.S. would reconsider its security arrangements with NATO members who refused to provide military support.

U.S. Administration

The United States views the Iran operation as a necessary response to regional threats and expects to achieve its objectives within weeks without ground troops. Rubio argued that allies benefit from American security commitments and should reciprocate by providing military support and base access when the U.S. faces crises, particularly regarding the Strait of Hormuz blockade.

European Perspective

European nations expressed concern about being excluded from decision-making on military operations and worry about becoming entangled in a protracted conflict without clear objectives or exit strategies. The EU emphasized the need for de-escalation and called for diplomatic solutions to prevent further global destabilization from the Middle East conflict.

  • The Strait of Hormuz is a critical global chokepoint through which roughly one-third of the world's seaborne oil passes.
  • Marco Rubio was previously a vocal NATO supporter before becoming Secretary of State, making his recent criticism of alliance commitments a notable shift.
  • The G7 comprises the world's seven largest advanced economies and represents a key forum for coordinating Western policy.

US-Iran Ceasefire War

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
