Seth Moulton on Nuclear Deterrence vs. Missile Defense

The Bedrock of Strategic Stability

• 💡 Nuclear weapons are presented as the foundation of strategic stability and deterrence against large-scale nuclear attacks from nations like Russia or China.
• 🎯 The concept of mutually assured destruction (MAD), while frightening, is argued to promote stability by ensuring nations face obliteration if they use nuclear weapons.
• ⚠️ If adversaries perceive the U.S. as less vulnerable to retaliatory strikes, it could embolden them to act preemptively or use novel delivery methods.

Missile Defense and Strategic Stability

• 🚀 The amendment aims to reaffirm existing policy, emphasizing that great power strategic stability is distinct from regional missile defense.
• 📉 While supporting missile defense for regional security and threats like drones and hypersonics, the amendment argues against undermining MAD with systems like "Golden Dome."
• 🛡️ The best missile defense systems offer about 95% protection, leaving a critical 5% vulnerability that could result in catastrophic destruction.
• 🛰️ The development of Russian space-based nuclear weapons capable of disabling "Golden Dome" with a single button is highlighted as a significant threat.

Bipartisan Consensus and Political Influence

• ✅ The amendment seeks to maintain a bipartisan consensus on nuclear deterrence that has been in place for over 70 years, supported by both Democratic and Republican administrations.
• 🚩 Concerns are raised that the focus on "Golden Dome" is driven by political rhetoric rather than strategic necessity.

Counterarguments and Fiscal Concerns

• 💰 Opposition argues that the amendment would retain an outdated policy focused on rogue states and refrain from countering threats from China or Russia.
• 📈 The underlying mark-up aims to update missile defense policy to counter all threats, regardless of source, citing Russia and China's own defensive capabilities.
• 💸 The proposed amendment to prohibit spending on space-based missile defense interceptors until costs and impact are clarified is met with opposition, citing the impossibility of estimating lifecycle costs before design work.
• 🚀 The Congressional Budget Office estimates the cost of space-based interceptors to range from $160 to $542 billion over 20 years, raising fiscal concerns.

The Arms Race and Future Threats

• 💥 The development of "Golden Dome" is seen by some as an invitation to an arms race, potentially making strategic stability worse.
• 🚢 Concerns are raised about novel delivery methods, such as Russia's sea-based nuclear-powered torpedo, which space-based interceptors may not counter.
• ⚛️ The repeal of the Anti-Missile Defense System treaty and subsequent increases in arms development by Russia and China are cited as evidence of the negative consequences of abandoning existing arms control frameworks.
• 📉 The ultimate goal should be to reduce nuclear proliferation, and policies that increase the likelihood of nuclear mistakes or arms races are counterproductive.
