Addressing Emerging Nuclear Challenges
As the Trump administration takes office, it will confront a world where nuclear competition is on the rise. The United States is preparing for multiple nuclear adversaries, each posing unique threats to strategic stability. The Biden administration highlighted these challenges, stating that the nation faces diverse nuclear threats that necessitate a robust deterrence strategy. However, the Trump administration might have limited opportunities to engage in arms control due to a lack of interest from key rivals like China and Russia.
China has shown little enthusiasm for engaging in arms control discussions with the U.S., while Russia has shelved the iconic New START Treaty, which capped the number of deployed nuclear warheads on long-range missiles and bombers. The treaty’s expiration in February 2026 could signal the end of these negotiated limitations, ushering in a new era of unconstrained nuclear competition.
Despite these challenges, the Biden administration has committed to maintaining New START limits as long as Russia complies and has expressed a willingness to explore arms control measures with responsible partners. Concurrently, the administration continues to modernize and potentially expand its nuclear forces, preparing for a scenario where nuclear constraints may no longer exist.
The Trump administration is likely to prioritize modernization and expansion of the U.S. nuclear arsenal, aligning with advisors who advocate for maintaining numerical superiority over combined Chinese and Russian nuclear stockpiles. However, the administration may show little interest in arms control initiatives similar to those pursued by the previous administration. During his first term, President Trump withdrew from several international agreements, including New START, citing Russian violations and the desire to free the U.S. from constraints.
Managing the Nuclear Competition with Russia
Limiting Deployed Nuclear Forces
Historically, the U.S. and Russia have relied on bilateral treaties to manage their nuclear arsenals. The establishment of a strategic stability dialogue aimed to lay the groundwork for future agreements, but the conflict in Ukraine interrupted these talks. President Trump could initiate informal discussions with Russia to maintain some form of nuclear restraint and transparency.
By reiterating the U.S. commitment to New START limits and encouraging Russia to do the same, Trump could foster some level of cooperation. Additionally, both nations could voluntarily share data on future deployments, enhancing predictability in their nuclear postures.
Addressing Emerging Risks
While formal treaty negotiations may be unlikely, U.S.-Russian cooperation could still focus on mitigating nuclear risks without limiting the number of warheads, missiles, and bombers. Initiatives like increased transparency, improved communication channels, and measures to prevent dangerous military operations could reduce tensions.
Identifying specific security threats that impact both nations and developing targeted mitigation strategies could lead to tangible benefits. For example, addressing concerns related to cyber threats, space-based assets, and conventional missile deployments could stabilize the nuclear competition.
Nuclear Weapons in Space
The U.S. is particularly concerned about Russia’s development of a nuclear-armed, space-based anti-satellite system. A nuclear explosion in space could devastate vital communications, surveillance, and military operations for the U.S. and its allies. Russia has denied such a program, but the potential risks warrant serious consideration.
The U.S. has worked with international partners to strengthen norms against nuclear weapons in space. However, direct dialogue with Russia on the dangers posed by these weapons could yield meaningful results. Both nations stand to benefit from reducing the instability and the risk of escalation posed by nuclear armed satellites.
Ballistic Missiles in Europe
The INF Treaty’s demise has led to increased deployments of medium- and intermediate-range missiles in Europe and Asia. President Trump’s administration plans to deploy conventionally armed INF-range missiles to Germany, while Russia has unveiled an intermediate-range missile of its own, the Oreshnik, as a direct response.
While neither side is likely to accept limitations on missile development, both nations can work to reduce the risks posed by these short-flight-time weapons. Measures such as prior notice of test launches, segregating nuclear and conventional missiles at different bases, and increased transparency in deployments could stabilize the situation.
Conclusion
U.S. nuclear policy under the Trump administration will require a balanced approach to modernize deterrence while exploring avenues for cooperative engagement with Russia. By addressing emerging nuclear challenges through both military strength and diplomatic initiatives, the U.S. can enhance its security posture while reducing the risks of nuclear conflict.
Looking ahead, the Trump administration should seek opportunities to find common ground with Russia on key nuclear issues. Initiating informal dialogues on limits, risks, space-based weapons, and missile deployments could pave the way for greater stability in the nuclear domain.
As the U.S. continues to navigate this complex security landscape, a pragmatic and flexible approach will be crucial. By combining military strength with diplomatic outreach, the Trump administration can better protect the nation while maintaining peace and security in a rapidly evolving nuclear world.
