Diplomatic Breakthrough and the Omission of Ballistic Missiles

In the Strait of Hormuz near Bandar Abbas, Iran, a significant diplomatic event unfolded on June 30, 2026. On this day, three leaders with differing interests acknowledged the same fact, leading the United States to declare a diplomatic breakthrough. The focus was on the omission of ballistic missiles in the U.S.–Iran Memorandum of Understanding.

Leaders’ Statements on Missiles

Pakistan’s Prime Minister, Shehbaz Sharif, commented that ballistic missiles “were never a subject of discussion.” Iranian President, Masoud Pezeshkian, emphasized that the missile file “never will be” part of any agreement. President Trump, speaking at the G7 in Evian, downplayed missiles as weapons that “hurt a little location” but “don’t blow up the planet.” Despite differing perspectives, these statements highlight a crucial omission in the memorandum.

The Memorandum of Understanding

The U.S.–Iran Memorandum of Understanding includes a single weapons-related commitment: Iran agrees not to develop nuclear weapons. Ballistic missiles, which Iran has used across the region as part of its deterrent strategy, are entirely omitted. This omission represents a key structural feature, not merely a minor detail to be negotiated later. Washington has chosen to exclude ballistic missiles, treating warheads and their delivery systems as separate negotiating tracks, whereas Iran sees them as integral to its defense.

Consequences of Excluding Ballistic Missiles

A nuclear program lacking missiles is limited to scientific research. Conversely, a missile program without nuclear warheads is an active military capability that Iran continues to utilize. The October 2024 missile attacks on Israel exposed limitations in intercepting such threats, even when most missiles are neutralized. The new agreement shields Iran’s missile capabilities from further diplomatic pressure.

Negotiation Dynamics

Washington prioritized signing an agreement over addressing missile threats. Iran maintained its negotiating stance, having presented a missile program intact and operational. Including missiles would have required consultations with key allies, potentially delaying or halting talks, so Washington chose speed over thoroughness.

Financial Implications

Iran anticipates access to $10–16 billion in frozen assets during a 60-day window. The sanctions relief provided without addressing missile constraints effectively funds Iran’s military infrastructure, enhancing its strike power. Iran’s missile industry relies on domestic manufacturing but lacks access to specific components, which sanctions relief helps supply.

Regional Reactions

Israel, Saudi Arabia, Qatar, and the UAE, primary targets of Iran’s missile potential, were never part of the consultation process. These allies are likely to pursue unilateral defense measures and build alliances with non-U.S. arms suppliers. The agreement shifts the focus of U.S. deterrence, prompting allies to consider self-insurance against threats Washington endorsed.

Iran’s Strategic Stance

For Iran, the missile program is essential for regime survival. While the nuclear program provides deterrence against existential threats, missiles deter conventional interventions and bolster power projection. Iranian negotiators achieved an agreement that endorses this doctrine, leaving missile capabilities unchallenged.

Future Negotiation Challenges

The current framework makes future missile negotiations unlikely, solidifying the notion that missiles are excluded from diplomatic discussions. Iran’s partial compliance with nuclear terms will increase pressure to maintain the agreement and prevent adding missile constraints.
