- India expanded its nuclear arsenal to an estimated 190 warheads by January 2026, up from 180 in 2025 per SIPRI, driven by its Pakistan rivalry and a strategic emphasis on countering China through MIRV deployment on the Agni-V IRBM and growing SSBN deterrence patrols.
- China grew its stockpile to 620 nuclear weapons by January 2026 from 600 in 2025, per SIPRI, with Mark Schneider at the National Institute for Public Policy arguing China could reach parity with the US — 1,770 deployed warheads — within four or five years.
- Operation Sindoor in May 2025 — Indian conventional strikes on Pakistani bases housing nuclear missions — became a key case for Rose Gottemoeller's Foreign Policy argument that nuclear retaliation failed to stop conventional or hybrid wars, with Patrick Cronin at the Hudson Institute adding that nuclear-armed states now exploit nuclear fears to achieve conventional goals while raising miscalculation risk.
- Pakistan is fusing gray zone warfare with nuclear deterrence per Ashok Shivane at CLAWS, using its nuclear posture to provide strategic insulation for proxy warfare and lower the nuclear threshold — while War on the Rocks authors report Pakistan is building AI-enabled multi-domain integration (electronic warfare, cyber, precision strikes) for escalation management.
- India strongly discounts Pakistan's nuclear threats per Siddhant Kishore in the Bulletin of the Atomic Scientists because Islamabad lacks a credible sea-based second-strike capability, though Richa Sharma at the United Service Institution warns China's advances in MIRVs, SSBNs, and counter-space systems could enable counterforce strikes against India's retaliatory forces.
- India-China border tensions remain structurally insulated from nuclear escalation by shared no-first-use policies and limited territorial stakes like eastern Ladakh, per Rakesh Sood at the Carnegie Endowment, meaning India responds to Chinese advances with conventional forces and deterrence by denial rather than nuclear signaling.
Why it matters: India's 190-warhead buildup buys survival-level deterrence, but the experts assembled here argue calibrated escalation control below the nuclear line — not warhead counts alone — will define the next phase. With Pakistan merging proxy warfare under its nuclear shield and China still focused on reaching US parity, New Delhi's hardest test is the gray zone it has to manage without anyone mistaking conventional pressure for nuclear brinkmanship.
