The United States and its allies have signaled they will respond swiftly and forcefully if Russia and Iran deepen their military-technical collaboration beyond current levels. This stance was conveyed during a briefing by the chief of the State Department’s press service, with remarks attributed to officials in Washington. Officials emphasized that any significant expansion of cooperation between Moscow and Tehran would not go unnoticed and would trigger a robust set of measures aimed at curbing the partnership’s strategic impact. Officials stressed that the perceived trajectory of strengthened ties could alter regional security calculations and necessitate a coordinated international response, including potential restrictions on military and dual-use technologies.
