Background

The US‑Iran missile standoff sits at the intersection of nuclear non‑proliferation, regional security and international sanctions regimes—key themes under GS‑II (International Relations) and GS‑III (Security Challenges). It reflects how great‑power rhetoric influences diplomatic negotiations, UN resolutions and regional stability in West Asia.

Mains Angle

GS‑II: Discuss the implications of US allegations and Iran's denial on the efficacy of the JCPOA and regional security architecture. The question may ask to evaluate the role of sanctions and diplomatic engagement in curbing missile proliferation.
