Nuclear War Risk & Stability Briefing – 1 December 2025 | DEFCON Warning System

This is The DEFCON Warning System Nuclear War Risk & Stability Briefing for 1 December 2025.

Global tensions continue to rise as shifting alliances, military postures, and regional conflicts shape the current nuclear risk environment.

In this briefing we cover:

South Korea’s warning of a “very dangerous situation” as inter-Korean tensions escalate

Iran’s denial of enrichment vs. satellite evidence of new weapons-linked construction

Russia’s offer of written guarantees not to attack Europe, met with Western scepticism

NATO’s discussions on a possible pre-emptive policy toward Russia

The stalled Ukraine peace process and its wider implications for European security

There are no imminent nuclear threats at this time, but several regions remain volatile and at risk of rapid escalation.

The DEFCON Warning System is a private intelligence organisation monitoring and assessing nuclear threats by national entities since 1984. We are not affiliated with any government agency and do not represent the alert status of any military branch.
