Key takeaways

  • Pickaxe Mountain in Iran sits 220 km south of Tehran in the Karkas Range and conceals deep underground nuclear facilities near Natanz.
  • The mountain's strong volcanic bedrock of andesite, rhyolite, and dacite offers Iran an asymmetrical strategic advantage against kinetic air strikes.
  • India tested its first nuclear device in 1974 under Smiling Buddha, driving Pakistan to accelerate its Kahuta uranium enrichment facility.
  • India chose strategic restraint in 1981 instead of striking Kahuta, eventually signing the Agreement on the Prohibition of Attack against Nuclear Installations in 1988.

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.
