# Nuclear Race 2026: The World on the Brink of an 'Instability Window' Without Control Treaties

The world stands on the brink of a dangerous era. According to the annual report by the Stockholm International Peace Research Institute (SIPRI), published in early 2026, the global nuclear arsenal continues to grow. Nine nuclear-armed states did not reduce their stockpiles during 2025; instead, they actively modernized them, striving to expand their military potential.

### Apocalyptic Figures: How Many Warheads Are There in the World?

As of January 2026, there are 12,187 nuclear warheads worldwide. This figure includes both strategic and tactical warheads. Of this total, 9,745 warheads are in military stockpiles, meaning they are ready for use if necessary. An even more alarming figure is the number of deployed warheads: 4,012 units are on missiles and aircraft.

Approximately 2,100–2,200 of the deployed warheads are on high alert 24/7 on ballistic missiles. This means they can be launched within minutes of receiving an order.

### Bipolar World and New Players

The traditional leaders of the arms race — Russia and the US — still dominate, controlling about 83% of the world's nuclear potential. However, their share is gradually shrinking as other powers actively expand their arsenals.

China is demonstrating the most aggressive growth dynamics. Beijing already possesses an arsenal of 620 warheads and is actively building new silo fields, expanding infrastructure for missile launches. Analysts predict that by 2030, China will surpass the psychologically significant mark of 1,000 warheads.

The West is not standing still either. France has announced its intention to increase its nuclear potential. The UK is restoring nuclear capabilities for its air force by purchasing F-35A fighters capable of carrying nuclear weapons. In the EU, the issue of expanding NATO's nuclear defense with the participation of Paris and London is being discussed with increasing activity.

### Russia: Modernization Despite Sanctions

SIPRI pays special attention to Russia's actions, which continue to modernize strategic forces despite harsh sanctions and colossal spending on the war in Ukraine. The year 2025 was contradictory for Russian developers.

Tests of the newest intercontinental ballistic missile 'Sarmat' ended in failure. However, the 'Burevestnik' cruise missile, which previously experienced technical difficulties, successfully passed tests, demonstrating a flight range of more than 14,000 kilometers.

Experts paid particular attention to Russia's start of construction of an advanced operational base for dual-use medium-range ballistic missiles 'Oreshnik' in Belarus. These missiles with conventional warheads have already been used against Ukraine; the last recorded strike occurred in May 2025.

### Korean Peninsula and Submarine Threats

On the other side of the world, in North Korea, leader Kim Jong Un personally visited a new nuclear materials production plant. According to Bloomberg, he ordered to increase the country's nuclear potential at 'exponential rates'.

Another alarming signal was the report on the actions of the Russian Northern Fleet. NATO intelligence tracked maneuvers that may indicate Moscow's attempt to place nuclear missiles on the seabed, creating a hidden threat to shipping and coastal areas.

### 'Instability Window'

SIPRI Director Karim Haggag warns that the combination of new technologies, geopolitical tension, and mutual distrust is forming an 'instability window' with long-term consequences for global security.

The main risk factor is the expiration of the New START treaty in 2026. This document was one of the key tools for nuclear arms control between Russia and the US. Its expiration without replacement by a new agreement leaves the world without legal mechanisms to limit the arms race.
