Nuclear Deterrence, Escalation & Arms Control
Topic
A live assessment of how this issue works in practice—institutions, tradeoffs, and what would improve outcomes. Evidence accumulates in our Summa.
Background
How nuclear signalling, doctrine, and arms-control collapse affect NATO crisis behaviour.
Why this remains an issue
- Russian nuclear rhetoric and exercises increased salience of escalation management
- NATO relies on US extended deterrence while some allies host dual-capable aircraft and shared burdens
- Arms-control architecture weakened; new treaties are politically difficult
- China’s arsenal growth adds global nuclear complexity beyond Europe
Core fault lines
- Deterrence vs proliferation: extended deterrence vs allies seeking independent options
- Signalling vs restraint: visible resolve vs escalation spiral risk
- Modernisation vs disarmament: credible forces vs non-proliferation norms
- Transparency vs ambiguity: public assurance vs strategic uncertainty

Why now

What to watch next
How should NATO communicate red lines without inviting brinkmanship? Would further arms-control be viable with Russia during active war?

Analysis
Decision tradeoffs
- Deterrence vs proliferation: extended deterrence vs allies seeking independent options
- Signalling vs restraint: visible resolve vs escalation spiral risk
- Modernisation vs disarmament: credible forces vs non-proliferation norms
- Transparency vs ambiguity: public assurance vs strategic uncertainty
Working view
- Nuclear policy must be discussed with crisis timelines and decision authority in mind
- Hybrid approach: maintain credible extended deterrence while pursuing selective risk-reduction measures
- Public education reduces both panic and complacency during crises
- Escalation control requires conventional options, not only nuclear threats
