History

• Started 1972 (Multan Conference, ZA Bhutto) — "even if we have to eat grass"
• Dr. A.Q. Khan — key figure, KRL (Kahuta Research Laboratories) uranium enrichment
• 1998: Chagai-I & Chagai-II nuclear tests (May 28 & 30) — response to Indian Pokhran-II tests
• Pakistan = 7th declared nuclear power; only Muslim-majority nuclear state

Doctrine

• Credible Minimum Deterrence (CMD) — enough capability to deter, not arms race
• Shifted toward Full Spectrum Deterrence post-2011 — covers strategic, operational, tactical levels (response to India's "Cold Start Doctrine")
• No formal "No First Use" policy (deliberate ambiguity, unlike India)
• Delivery systems: Shaheen & Ghauri missile series (land), Babur cruise missile, naval-based options (Babur-3)

Command & Control

• National Command Authority (NCA) — apex civil-military body overseeing nuclear policy
• Strategic Plans Division (SPD) — operational custodian, security & safety
• Robust Personnel Reliability Program (PRP) for those with access

Safety & Security

• Not a signatory to NPT or CTBT — argues discriminatory treatment
• International concerns: proliferation risk (post A.Q. Khan network exposure, 2004), terrorism-adjacent instability, tactical nukes lowering threshold
• Pakistan counters: strong C2 systems, IAEA cooperation on civilian side, NSG membership bid (blocked, largely due to NPT non-signatory status & India-Pakistan rivalry)

International Concerns

• Western worry over tactical nuclear weapons (battlefield use lowers escalation threshold)
