“The SIPRI Yearbook is known worldwide as an authoritative and independent source for politicians, diplomats, journalists, scholars, students and citizens on armaments, disarmament and international security. It provides an overview of developments in international security, weapons and technology, military expenditure, the arms trade and arms production, and armed conflicts, along with efforts to control conventional, nuclear, chemical and biological weapons. Key findings of SIPRI Yearbook 2026 are that states are increasingly relying on nuclear weapons as instruments of national power—reversing decades of efforts to reduce the numbers and role of nuclear weapons—even as the risks of miscalculation and escalation are rising.“
