The Nuclear Arms Race: What Happens Now That New START Has Lapsed?
The expiration of the New START treaty on February 5th marks a pivotal – and deeply concerning – moment in international security. For decades, this agreement between the United States and Russia provided a crucial framework limiting the deployment of strategic nuclear weapons. Its lapse doesn’t immediately trigger a surge in warheads, but it removes a vital layer of predictability and transparency, significantly increasing the risk of a renewed arms race. The world hasn’t felt this level of uncertainty since the Cold War.
A History of Control: From SALT to New START
The New START treaty wasn’t an isolated event. It was the latest in a series of arms control agreements stretching back to 1972 with the Strategic Arms Limitation Talks (SALT I). These treaties, born from the terrifying logic of Mutually Assured Destruction (MAD), aimed to manage – not eliminate – the nuclear threat. Each iteration built upon the last, establishing verification mechanisms and numerical limits. New START, signed in 2010, capped deployed strategic nuclear warheads at 1,550 per country, with limits on delivery systems like ICBMs and bombers. The treaty’s verification regime, including on-site inspections, was particularly valuable, fostering trust and reducing the potential for miscalculation.
Why Did New START Fail to Renew? The US Perspective
Russia offered an extension, but the US didn’t formally respond. The reasons are complex, but a key factor is China. Unlike the US and Russia, China is rapidly expanding its nuclear arsenal. As of late 2023, estimates put China’s nuclear warhead stockpile at over 500, with projections exceeding 1,000 by 2030, according to the Stockholm International Peace Research Institute (SIPRI). Some US policymakers argue that a bilateral treaty with Russia is insufficient, as it doesn’t address this growing threat. They advocate for a trilateral agreement including China, but Beijing has consistently resisted joining such talks, citing the comparatively smaller size of its arsenal.
Another contributing factor was the breakdown in verification. Russia halted US inspections in 2023, citing US support for Ukraine as a pretext. This lack of transparency eroded trust and made it harder to justify extending the treaty without guarantees of reciprocal access.
The Impact of the Ukraine War
The war in Ukraine has dramatically altered the geopolitical landscape. Russia’s rhetoric, including veiled threats of nuclear use, has heightened tensions and further strained relations with the West. While the US and Russia both maintained they would adhere to New START’s limits even without the treaty in force, the absence of verification mechanisms increases the risk of both sides exceeding those limits undetected. This creates a dangerous environment where miscalculation could have catastrophic consequences.
Did you know? The US currently maintains approximately 3,700 nuclear warheads, including both deployed and non-deployed weapons. Russia’s stockpile is estimated to be similar in size.
What’s Next? Potential Future Trends
Several scenarios are possible. A complete collapse of arms control is a real danger. Without any constraints, both the US and Russia could significantly increase their nuclear arsenals, leading to a new and destabilizing arms race. This could also incentivize other nations to develop or acquire nuclear weapons, further increasing global risk.
However, there’s still a possibility of future negotiations. Despite the current impasse, both sides have expressed a willingness to engage in dialogue. A potential path forward could involve a broader agreement that addresses China’s nuclear buildup, but achieving this will require significant diplomatic effort and a willingness from all parties to compromise.
Another trend to watch is the development of new nuclear technologies. Hypersonic weapons, for example, pose a particular challenge to existing arms control frameworks due to their speed and maneuverability. These technologies could further destabilize the nuclear balance and increase the risk of escalation.
The Role of China: A Key to Future Stability
China’s participation in arms control talks is crucial. Without Beijing at the table, any agreement between the US and Russia will be incomplete and less effective. However, persuading China to join negotiations will require addressing its concerns about the US’s existing nuclear capabilities and its strategic alliances in Asia. This will be a complex and challenging undertaking.
Pro Tip: Stay informed about developments in nuclear arms control by following organizations like the Arms Control Association and the Stockholm International Peace Research Institute (SIPRI).
FAQ: New START and the Future of Nuclear Arms Control
- What happens now that New START has expired? The treaty’s formal limits are no longer legally binding, but both the US and Russia have stated they will continue to share data on their nuclear forces for now.
- Is there a risk of a nuclear war? The risk has increased due to the lack of transparency and predictability.
- Will China join arms control talks? Currently, China is reluctant, but pressure is mounting for its participation.
- What are hypersonic weapons and why are they a concern? Hypersonic weapons are extremely fast and maneuverable, making them difficult to intercept and potentially destabilizing.
