Marco Rubio questioned why allies including Italy are not backing U.S. efforts to confront Iran and reopen the Strait of Hormuz.

The friction highlights a growing divide between Washington and its European partners regarding the level of military and diplomatic pressure required to secure global shipping lanes.

Rubio met with Italian Prime Minister Giorgia Meloni in Rome earlier this week to discuss the escalating tensions. During the visit, Rubio said the United States needs its European allies to support its response to Iranian actions that threaten the Strait of Hormuz [1]. The discussions occurred as the conflict involving Iran continues to strain ties between Italy and the U.S. [2].

While the U.S. has pushed for a more aggressive stance to ensure the waterway remains open, some European nations have shown hesitation to fully commit to a potential military response. Rubio said that the stability of the region depends on a unified front among allies [1].

Reports of the meeting surfaced on May 8, 2026 [2]. The dialogue in Rome underscores the difficulty Washington faces in coordinating a multilateral strategy against Tehran. Rubio said that the current lack of full alignment from allies complicates the U.S. objective of restoring free navigation in the region [1].

Italy has maintained a complex relationship with the region, balancing its economic interests with its security obligations to the U.S. The meeting with Meloni served as a direct attempt to resolve these discrepancies in strategic priorities [1], [3].

“The U.S. needs its European allies to support its response to Iranian actions.”

The public questioning of an ally by a high-ranking U.S. official suggests that private diplomatic channels are failing to produce a consensus on Iran. If the U.S. cannot secure European backing for the reopening of the Strait of Hormuz, it may be forced to act unilaterally, which could further isolate Washington or increase the risk of a wider regional conflict.
