Why in News

  • The US threatened military action against Iran due to reports that **Pickaxe Mountain** hides deep underground facilities for Iran's nuclear programme.
  • This situation has restarted debate on India's decision in the **1980s** to avoid a pre-emptive strike on Pakistan's **Kahuta uranium enrichment facility**.

Geological and Strategic Features of Pickaxe Mountain

  • **Pickaxe Mountain** is located about **220 km south of Tehran** near **Natanz** within the **Karkas Range**, which spans over **100 km** between **Kashan and Ardestan**.
  • The mountain range belongs to the **Urumieh-Dokhtar magmatic belt**, created when the **Neo-Tethyan Ocean** subducted under the Iranian plate over the last **66 million years**.
  • The bedrock consists mainly of tough volcanic rocks like **andesite, rhyolite, and dacite**, along with **pyroclastic deposits and volcanic tuffs**.
  • Complex internal networks of **fault zones and varying rock densities** scatter kinetic shockwaves, making military blast penetration hard to calculate.
  • The thick volcanic layers provide natural underground protection, giving Iran an **asymmetrical strategic advantage** near vital sea lanes like the **Strait of Hormuz**.

India's Kahuta Dilemma and Nuclear Restraint

  • India conducted its first nuclear test **Smiling Buddha** in **1974** at Pokhran, which led Pakistan to speed up work on its **Kahuta uranium enrichment facility**.
  • The **Indian Air Force** evaluated the possibility of a pre-emptive strike on Kahuta in **1981**, but India never launched an official military attack.
  • India chose **strategic restraint**, allowing Pakistan to gain **nuclear capability by the late 1980s**, which changed the strategic balance of South Asia.
  • To reduce risks to nuclear plants, India and Pakistan signed the **Agreement on the Prohibition of Attack against Nuclear Installations and Facilities in 1988**.
  • Both countries have **annually exchanged lists of their nuclear installations** every year since **1992**.
  • Today, India follows a strategy of **credible minimum deterrence** while strengthening its air defence through modern systems like **Project Kusha** and **Sudarshan Chakra**.
