Nuclear Brinkmanship Returns as New START Treaty Lapses

The Lapsed New START Treaty

• 🎯 The New START treaty, the last arms control agreement between the US and Russia, has lapsed after being in force for 15 years.
• 🔑 This treaty limited the number of deployed nuclear warheads and delivery systems for both superpowers, who collectively hold nearly 90% of the world's atomic warheads.
• ✅ The treaty was highly effective, with both nations largely adhering to its terms, including transparency measures, even after geopolitical tensions rose.

Immediate Consequences of the Lapse

• 📈 Both Russia and the US are expected to increase their deployed nuclear warheads by uploading stockpiled warheads onto existing delivery systems.
• 🚀 The US could nearly double its deployed warheads, while Russia could increase theirs by about 1.5 times, leading to a significant increase in destructive power.
• ⚠️ This escalation is seen as an easy step, not necessarily involving the development of new weapons, but rather maximizing the use of existing arsenals.

Broader Arms Race Concerns

• 🌍 The lapse of New START removes a key guardrail, potentially incentivizing an arms race among nuclear powers.
• 🇨🇳 China, which has been expanding its arsenal, may accelerate its buildup in response to increased US and Russian deployments.
• 🇮🇳 India and 🇵🇰 Pakistan could follow suit, creating a domino effect of nuclear proliferation.
• 🌍 Geopolitical instability and a perceived lack of US support could even prompt non-nuclear nations to consider developing their own arsenals.

Future of Arms Control

• ❓ Negotiating a new treaty, especially one that includes China, presents significant challenges due to differing arsenal sizes and geopolitical dynamics.
• ⏳ The window for negotiating a replacement treaty has passed, leaving controls on nuclear weapons in a state of uncertainty.
• 🚨 The world is entering a new, potentially more dangerous era for nuclear weapons, with the Doomsday Clock now closer to midnight than ever before.
