Nuclear Weapons Policy: How Democrats, Republicans, and the Common Good Plan Actually Compare

Nuclear weapons are the most destructive technology ever created. A single modern warhead can destroy an entire city. A full-scale nuclear exchange between the US and Russia would kill hundreds of millions directly and trigger a nuclear winter that could cause global famine affecting billions. The Bulletin of the Atomic Scientists' Doomsday Clock stands at 90 seconds to midnight — the closest to nuclear catastrophe in its history. Yet nuclear weapons policy receives almost no attention in American political discourse.

The last remaining nuclear arms control treaty between the US and Russia — New START — is set to expire in 2026 with no successor agreement. Russia has suspended its participation. China is rapidly expanding its nuclear arsenal from roughly 350 to an estimated 1,000-1,500 warheads by 2035. The US is spending $1.5-2 trillion on nuclear modernization over 30 years. Arms control is collapsing at the exact moment when the risk of nuclear use — through the Ukraine conflict, Taiwan tensions, or miscalculation — is higher than it has been in decades.

Democrats generally support arms control and some restraint. Republicans favor strength through modernization with minimal arms control. The Common Good Party proposes a comprehensive framework: maintain credible deterrence, adopt no first use, reform launch authority, pursue new arms control agreements, and redirect savings from an oversized arsenal toward conventional defense and domestic priorities.

How the three approaches stack up on nuclear weapons policy.

What they propose

Democrats generally support arms control, are open to arsenal reductions, and have pursued diplomatic solutions to proliferation challenges (the Iran nuclear deal). Some Democrats support no first use and shared launch authority. The party supports CTBT ratification and has sought to limit some nuclear modernization programs. However, Democratic administrations have also funded the core modernization program and maintained nuclear ambiguity on first use.

What it gets right

Democrats correctly prioritize arms control as essential to long-term security. The party's support for CTBT ratification and New START extensions has preserved the arms control architecture that reduced arsenals from 70,000+ warheads to roughly 12,000. Diplomatic approaches to proliferation — including the Iran nuclear deal — have been more effective than threats alone. And the growing Democratic support for no first use and launch authority reform reflects serious engagement with the most dangerous gaps in nuclear governance.

What it misses

The party is internally divided and has not translated its rhetoric into policy. Democratic administrations funded the full nuclear modernization program while expressing reservations. No first use remains a minority position within the party. The party has not forced the hard conversation about whether all three legs of the nuclear triad are necessary when submarine-based deterrence alone is sufficient. And Democrats have not articulated a clear vision for bringing China into the arms control framework — a critical gap as China's arsenal grows.

What they propose

Republicans favor peace through strength — maintaining and modernizing all three legs of the nuclear triad, opposing arms control agreements that constrain US flexibility, maintaining sole presidential launch authority, preserving nuclear ambiguity on first use, and expanding missile defense. The party withdrew from the INF Treaty (2019), opposes CTBT ratification, and argues that any arms control agreement must include China. Republicans support full funding for nuclear modernization and have proposed new nuclear capabilities.

What it gets right

A credible nuclear deterrent is essential to American security. Russia's invasion of Ukraine — which occurred partly because Ukraine gave up its nuclear weapons — validates the importance of deterrence. The demand to include China in future arms control frameworks is strategically sound as China's arsenal grows. And some elements of modernization are genuinely necessary — aging systems must be replaced to maintain reliability and safety.

What it misses

There is no scenario where the US needs 5,000+ nuclear warheads. Even 1,000 deployed warheads — enough to destroy any adversary many times over — provides overwhelming deterrence. Spending $1.5-2 trillion on modernizing an oversized arsenal diverts resources from conventional capabilities that are more likely to be used. Opposing all arms control increases the risk of an unconstrained arms race with Russia and China. And maintaining sole presidential launch authority for first use means a single individual — under no constraint — can make the most consequential decision in human history in minutes.

The argument that arms control constrains American flexibility ignores that it also constrains adversaries. Without New START, Russia could deploy far more warheads targeting American cities. Arms control is not weakness — it's mutual constraint that benefits both sides.

What we propose

The Common Good Party proposes a nuclear policy built on four principles: maintain credible deterrence at lower force levels, reduce the risk of accidental or unauthorized use, pursue arms control as a strategic priority, and redirect savings to more pressing defense and domestic needs. Specifically: reduce to 1,000 deployed warheads (still sufficient for overwhelming deterrence); adopt no first use; require two-person concurrence for first-use launch orders; negotiate a New START successor and begin trilateral talks with China; ratify the CTBT; prioritize submarine-based deterrence while evaluating whether the full ICBM modernization is necessary; and redirect savings toward conventional military capabilities, cybersecurity, and domestic priorities.

Why it's different

Unlike the Democratic approach, we take clear positions on no first use, launch authority reform, and force reduction rather than hedging. Unlike the Republican approach, we recognize that 5,000+ warheads and $2 trillion in modernization spending are not strength — they're waste and risk. The CGP plan maintains a nuclear deterrent that no adversary can overcome while reducing the probability of the catastrophe that deterrence is meant to prevent. Every additional warhead above what's needed for deterrence increases cost and risk without increasing security.

The evidence

Multiple independent analyses — including from former Secretaries of Defense, Joint Chiefs chairs, and nuclear strategists — have concluded that the US could maintain credible deterrence with a significantly smaller arsenal. A single Ohio-class submarine carries enough warheads to destroy an entire country. The US has 14 of them. The British nuclear deterrent — which no one doubts — consists of 225 warheads, less than 5% of America's arsenal. Deterrence requires the certainty of unacceptable retaliation, not 5,000 warheads. The Cold War is over. Our nuclear policy should reflect that reality.

Nuclear policy may feel abstract, but it affects your safety, your taxes, and your future. Here's what the CGP approach means.
