The New Nuclear Age: Russia, China, and Global Nuclear Strategy

The Dawn of a New Nuclear Age

• 💡 We are entering a new nuclear age, characterized by the return of great power competition and the central role of nuclear weapons.
• ⚡ Unlike the first Cold War, the US and its allies now face two peer nuclear superpowers – Russia and China – simultaneously.
• 🎯 Nuclear weapons remain the ultimate instrument of military force, capable of destroying societies rapidly, a capability unmatched by cyber or other technologies.

China's Massive Nuclear Buildup

• 🚀 China is engaged in the most significant nuclear buildup since the 1960s, expanding its arsenal from around 200 to a projected 1,500 nuclear weapons.
• ⚠️ This buildup is driven by theories, including the plausible idea that China aims to deter US intervention in a potential invasion of Taiwan.
• 📈 China is observing Russia's nuclear threats in Ukraine and believes similar tactics can be used to influence Western responses and limit intervention.

Nuclear Strategy in a Multipolar World

• 🗺️ The US faces fundamental questions about nuclear strategy, force posture, and numbers due to the rise of China as a nuclear peer.
• 🌍 The proliferation of nuclear capabilities extends to North Korea and potentially Iran, further complicating the global security landscape.
• 🚢 In a Taiwan conflict scenario, China might use a blockade or a full-scale invasion, with the US and allies needing to counter amphibious assaults, all under the shadow of nuclear weapons.

Technological Advancements and Nuclear Escalation

• 🛰️ Advanced intelligence, surveillance, and reconnaissance (ISR) systems may offer better awareness of an adversary's nuclear movements.
• ✈️ Recent drone attacks on Russian strategic bombers raise questions about whether new technologies could enable disarming strikes on an opponent's strategic forces.
• 💥 The nuclear triad (bombers, ICBMs, submarine-based missiles) remains crucial, with each leg possessing unique attributes vital for deterrence.

Deterrence and Extended Nuclear Posture

• 🇬🇧🇫🇷 British and French nuclear weapons matter for deterring attacks on their respective nations and complicate calculations for potential adversaries like Russia.
• 🇺🇸 However, only the US possesses the scale and robustness to extend nuclear deterrence over a vast network of allies, covering a significant portion of global GDP and key regions.
• 🛡️ Strengthening deterrence, both conventionally and strategically, is paramount. This includes a potential US nuclear buildup, increased conventional defenses in Europe, and maintaining a strong US nuclear umbrella to discourage allies from developing their own nuclear weapons.
