In a chilling reminder of Cold War-era tensions, the Stockholm International Peace Research Institute (SIPRI) has released its 2025 Yearbook, nuclear arms race revealing a dramatic expansion of nuclear arsenals worldwide. According to the report, nine nuclear-armed states are not only maintaining but actively modernizing their arsenals, escalating the risk of global catastrophe.
📊 Global Nuclear Stockpile in 2025
SIPRI estimates there are 12,121 nuclear warheads globally as of January 2025, with 9,585 in military stockpiles. Of those, roughly 2,100 are on high operational alert, mostly held by the United States and Russia. This marks the first significant growth in global nuclear weapon count in over a decade nuclear arms race.
🚀 The Countries Driving the Arms Build-Up
- 🇺🇸 United States: Possesses around 5,244 warheads. Major upgrades underway in submarine-launched ballistic missiles and B-21 bombers. (Arms Control Association)
- 🇷🇺 Russia: Owns approx. 5,580 warheads, testing hypersonic delivery systems and new intercontinental missiles like the Sarmat.
- 🇨🇳 China: The most rapidly expanding arsenal, now at 500+ warheads. Building over 300 ICBM silos. (Reuters)
- 🇮🇳 India: Expanding MIRV (Multiple Independently targetable Reentry Vehicle) missile systems; approx. 170 warheads.
- 🇵🇰 Pakistan: ~170 warheads, advancing tactical nuclear weapons.
- 🇰🇵 North Korea: Estimated 50–70 warheads, with increasing missile tests and threats to the U.S. and South Korea.
⚠️ Arms Control Treaty Breakdown
The global security framework is weakening. Key arms treaties are eroding:
- New START Treaty between the U.S. and Russia is set to expire in 2026 with no extension in sight.
- The INF Treaty and the Open Skies Treaty have collapsed.
- The Comprehensive Nuclear-Test-Ban Treaty (CTBT) remains unratified by key states, limiting enforcement. (CTBTO)
🤖 AI, Hypersonics, and Space-Based Risks
Modern technologies are heightening nuclear dangers. SIPRI warns that artificial intelligence, hypersonic missiles, and cyber-warfare could reduce decision-making time and increase the chance of miscalculations or false alarms. Space-based surveillance systems are also becoming targets, further destabilizing deterrence strategies.
💰 Skyrocketing Global Nuclear Spending
According to the International Campaign to Abolish Nuclear Weapons (ICAN), global nuclear weapons spending surged by 13% in 2024, totaling over $91 billion. The U.S. alone spent $50 billion, more than all other nuclear powers combined.
🌍 Growing Regional Tensions
- Eastern Europe: NATO nuclear sharing discussions resurface amid the Russia-Ukraine conflict.
- Middle East: Iran’s nuclear enrichment activities are under fresh scrutiny. Israel continues strategic ambiguity.
- South Asia: India-Pakistan rivalry intensifies with new missile capabilities and border skirmishes.
📢 Conclusion: The World on the Brink
SIPRI’s warning is clear: We are entering a dangerous era of nuclear competition. Without immediate international cooperation and treaty reinforcement, the world risks sliding into an uncontrollable arms race with catastrophic consequences.
