Why is Iran's nuclear program central to its diplomacy?

• A. It shapes relations with the US and Europe, justifies sanctions, and tests the regime's bargaining power; decisions involve the Leader and security services.
• B. It is only a domestic issue with no international impact.
• C. It has no bearing on diplomacy.
• D. It is supported by all regional actors.

Answer: (A)

The central idea is that Iran’s nuclear program is a powerful tool in its foreign policy because it directly affects security, sanctions, and bargaining leverage. How Iran handles negotiations with the United States and Europe is heavily shaped by the nuclear issue, since Western powers tie sanctions relief, security guarantees, and compliance assurances to limits on nuclear activities. By showing progress or pauses in its program, Iran uses it to press for concessions and relief, testing what it can extract while preserving its strategic red lines.

In Iran’s political system, decisions about diplomacy and security are not simply driven by the president or ministries; the Supreme Leader has the final say, and security organs like the IRGC and intelligence services play influential roles. That means the nuclear question is deeply intertwined with who holds power and how foreign policy is conducted, making the program a core factor in diplomacy rather than a purely domestic matter.

This isn’t universally supported by regional actors, and it isn’t irrelevant to diplomacy. That’s why the nuclear issue stands at the center of Iran’s international relations, rather than being an isolated domestic concern or a uniformly embraced regional stance.
