In a recent announcement, U.S. Secretary of State Marco Rubio expressed concerns over Iran's efforts to develop intercontinental ballistic missiles that could potentially target the United States. He characterized Tehran's missile program as a significant and "unsustainable threat". During his statements in Basseterre, Saint Kitts and Nevis, Rubio highlighted that Washington has observed Iran expanding the operational range of its missile arsenal, and he underscored Iran's ambition to produce weaponry with the capability of reaching American territory.

Rubio noted that Iran already possesses weapons capable of threatening a large portion of Europe, and he expressed surprise at Tehran's continued investments in long-range missiles, particularly in light of crippling sanctions and serious economic hardships facing the nation. As a national security advisor to President Donald Trump, Rubio articulated the gravity of the situation, linking Iran's military advancements to broader regional stability concerns.

As new rounds of U.S.-Iran negotiations loom in Geneva, Rubio remained firm in the belief that diplomacy is always preferable, stating that it has never been wholly dismissed. He reiterated President Trump's inclination towards diplomatic solutions, emphasizing the need for a nuanced approach to the challenges presented by Iran's missile capabilities and broader geopolitical aims.
