Trump Backs Extension of New START Treaty to Curb Nuclear Arms Race

On July 25, 2025, U.S. President Donald Trump expressed support for maintaining the New START nuclear arms limits with Russia, emphasizing the global risks if the treaty expires on February 5, 2026, without replacement. The Arms Control Association urged immediate negotiations between Trump and Vladimir Putin to reach an interim agreement, warning that failure could lead to both nations increasing deployed nuclear arsenals for the first time in over three decades. Sustaining and advancing arms reduction frameworks remains critical to preventing escalating nuclear tensions and preserving global security.

Background & Context

The Russia nuclear threat remains a critical concern amid the ongoing geopolitical tensions and the broader Russia Ukraine war. Central to current nuclear stability is the New START treaty, signed in 2010, which serves as the last remaining bilateral arms control agreement limiting deployed strategic nuclear weapons between the United States and Russia. This treaty has played a vital role in maintaining decades of nuclear stability by capping deployed warheads and launchers on both sides.

With the treaty’s expiration approaching and no new agreement or interim extension yet formalized, there are growing fears that both nations may expand their nuclear arsenals, thus increasing global risks of nuclear escalation. Although the Trump administration expressed openness to arms reductions, formal negotiations have not commenced, and political as well as strategic challenges complicate progress. Maintaining strong nuclear arms control agreements remains essential for global security and nonproliferation efforts, particularly given the evolving Russia NATO tensions and heightened military confrontations.

Key Developments & Timeline

2010: The New START treaty was signed between the United States and Russia, establishing limits on deployed strategic nuclear arsenals and entering into force, marking a significant milestone in arms control.
Prior to 2025: The New START treaty was extended and implemented, continuing to serve as the last bilateral nuclear arms reduction agreement between the two powers amidst growing Russia NATO tensions and geopolitical challenges.
July 25, 2025: President Donald Trump publicly expressed his commitment to maintaining the New START limits with Russia, emphasizing the importance of ongoing nuclear arms control to reduce global nuclear threats.
February 5, 2026: The New START treaty is scheduled to expire unless extended or replaced. Without a new agreement, there is a significant risk that both the United States and Russia could escalate their nuclear arsenals for the first time in over 35 years, exacerbating the global security environment.

This timeline highlights the critical juncture in bilateral nuclear arms control amid rising Russia nuclear threat concerns related to the broader Russia geopolitical conflict. The expiration of New START could lead to increased nuclear proliferation and destabilize decades of disarmament progress.

Experts and the Arms Control Association urge an interim deal to sustain existing limits until a new framework is negotiated. Prompt action by leaders such as President Trump and Vladimir Putin is essential to prevent a renewed nuclear arms buildup and to uphold strategic stability between the United States and Russia.

Official Statements & Analysis

On July 25, 2025, U.S. President Donald Trump voiced his support for maintaining the strategic nuclear arms limits outlined in the New START treaty with Russia, which is set to expire on February 5, 2026. Trump emphasized the global risks posed by allowing these nuclear restrictions to lapse and expressed a willingness to continue arms reduction negotiations. The Arms Control Association highlighted the mutual interest of the United States, Russia, and the world in preserving these limits to prevent a renewed nuclear arms race. They warned that without an interim deal or a new framework, both nations could begin increasing their deployed nuclear arsenals for the first time in over 35 years, significantly elevating nuclear threats.

This treaty expiration represents a critical point in Russia geopolitical conflict management and nuclear arms control. The need for immediate, concrete negotiations between Trump and Russian President Vladimir Putin to translate rhetoric into action is crucial for sustaining strategic deterrence and global security. Failure to agree on continued arms control could escalate geopolitical instability and increase the risk of nuclear escalation, underscoring the urgency of diplomatic efforts to avert a dangerous proliferation scenario.

Conclusion

As the Russia Ukraine war continues to impact global security, the looming expiration of the New START treaty in early 2026 raises urgent concerns over nuclear arms control. U.S. President Donald Trump’s expressed support for maintaining strategic nuclear limits underscores the critical need to prevent a renewed nuclear arms race between the United States and Russia. Without timely interim agreements and comprehensive negotiations, the risk of escalating nuclear threats grows, heightening geopolitical instability. Sustained diplomatic efforts are essential to safeguard global security and reduce the dangers posed by expanding nuclear arsenals.
