The New Nuclear Arms Race: Putin, Xi, Trump, and Global Security

The Resurgence of Nuclear Weapons

• ☢️ Nuclear weapons are experiencing a resurgence in global discourse, marked by Russia's withdrawal from the INF Treaty and the US increasing its nuclear submarine presence near Russia.
• 🌍 The trend is further evidenced by growing stockpiles in China and North Korea, and increased cooperation between the UK and France.
• 🕊️ The 80th anniversary of the Hiroshima and Nagasaki bombings serves as a stark reminder of the devastating consequences of nuclear warfare, with a warning from Hiroshima's mayor about a global trend towards military buildup and the perceived necessity of nuclear weapons.

Understanding Nuclear Deterrence and Arsenals

• ⚛️ A nuclear weapon can be a fission or fusion device, varying in yield and delivery mechanisms, with deterrence being their primary function.
• 🇺🇸🇷🇺 Russia and the United States possess the largest nuclear arsenals, each with over 5,000 warheads, though China is rapidly increasing its stockpile to an estimated 1,000 warheads by 2030.
• 🇬🇧🇫🇷🇮🇱🇮🇳🇵🇰🇰🇵 Other nuclear states include the UK, France, Israel, India, Pakistan, and North Korea.
• 🎯 Deployed nuclear warheads are those ready for immediate use, a fraction of total capacity, with the US and Russia maintaining around 1,550 each.

Tactical vs. Strategic Nuclear Weapons and Doctrine

• 💥 Tactical nuclear weapons have smaller yields and shorter ranges, intended for battlefield use, while strategic weapons are larger and longer-range.
• 🇷🇺 Russia has developed a doctrine for the flexible use of nuclear weapons as a coercive tool, aiming to inflict damage that gives an opponent pause without necessarily escalating to full-scale nuclear war.
• 🇺🇸 NATO is re-evaluating its nuclear posture to counter Russia's lead in theater-range nuclear weapons and address a gap in its escalation ladder.

Collapse of Arms Control Treaties

• 📜 The collapse of arms control treaties like the INF is attributed to Russia's non-compliance and the shift from a bipolar to a multipolar world, where treaties designed for two powers are structurally unsuited.
• 🇨🇳 China's significant arsenal of medium and intermediate-range ballistic missiles, which are not nuclear but can be used conventionally against high-value targets, further complicates the arms control landscape.
• 🚀 The US plans to deploy intermediate-range missiles like Dark Eagle and Typhon, signaling a ratification of reality after treaty violations by both sides.

Nuclear Posture and Signaling

• 📍 A nuclear posture defines a nation's distribution of capabilities, including missiles, warheads, management, and command and control mechanisms.
• 📣 Nuclear signaling, such as changing alert status or repositioning forces, is an unusual but not unprecedented tool used to convey messages to adversaries, though its use on social media is novel.
• 🤝 The UK and France's greater nuclear cooperation signals a potential shift towards employing European nuclear arsenals as an alliance asset rather than purely national capabilities.

Nuclear Weapons as Insurance and Enablers

• 🛡️ For some states, nuclear weapons are a means of ensuring against existential threats, particularly for regimes like North Korea, driven by fears of regime change.
• 🇵🇰 Pakistan's nuclear weapons have enabled it to sponsor state-backed terror in India, deterring conventional retaliation.
• 🇮🇷 The fear of Iran acquiring nuclear weapons is not just about its use, but about emboldening the regime to become more aggressive with proxies, knowing it has insurance against conventional attack.
