Background

Overview

This concept is critical for understanding global security, the role of international organizations like the IAEA and UNSC in maintaining peace, the effectiveness of non-proliferation treaties, and the geopolitical stability of the Middle East. It reflects the complex interplay of diplomacy, sanctions, and security concerns.

Iran's nuclear program has been a long-standing international concern regarding its potential for weaponization, leading to various international agreements and monitoring efforts.
