Global Security Trends Shift As Nuclear Powers Modernize
The Stockholm International Peace Research Institute (SIPRI) has released its annual assessment of global armaments, disarmament, and international security, highlighting a growing focus on nuclear weapons amid heightened escalation risks. The SIPRI Yearbook 2026 reports that the nine nuclear-armed states continued to modernize and enhance their nuclear arsenals in 2025, with the global inventory of nuclear warheads potentially increasing in the coming years. This development is attributed to advances in weapon technology, the breakdown of nuclear arms control, and heightened geopolitical tensions. The SIPRI Yearbook 2026 was published by Oxford University Press, as reported by the Stockholm International Peace Research Institute.
