UNITED NATIONS, Nov 6 2025 (IPS) – In recent days, nuclear state leaders have flouted the regulations and norms around nuclear non-proliferation and are flirting more openly with nuclear might in the name of projecting strength.

In the last week, the United States and the Russian Federation have made public shows of their nuclear messaging. On the 27th of October, President Vladimir Putin revealed a new nuclear-powered missile capable of staying airborne far longer than conventional missiles and even evading missile defense systems. Some experts have suggested that this is meant to reinforce Russia’s nuclear might, which Putin has leaned on since the start of the Ukraine invasion in February 2022.

More recently, on 29 October, President Donald Trump announced via social media that he wanted to resume nuclear testing for the first time in thirty years. In his post he wrote, “Because of other countries testing programs, I have instructed the Department of War to start testing our Nuclear Weapons on an equal basis.”

As he made this announcement just before his meeting with President Xi Jinping, some experts have considered that China’s expanding nuclear arsenal has prompted some calls in Washington D.C. to quickly modernize the U.S.’s own nuclear forces. Nuclear testing by major powers like China, Russia or the U.S. has not been conducted in decades. Yet analyses have warned that such an act would only further complicate relations between this triad.

All these developments should not come as a surprise. Even as countries have been aware of the dangers of nuclear weapons since 1945, this has not completely stopped them from expanding their forces. As of June 2025, there are over 12,400 nuclear warheads in the world in only a small percentage of countries. The U.S. and Russia account for 90 percent of those warheads, both possessing more than 5,000 nuclear warheads. According to the Stockholm International Peace Research Institute (SIPRI), nearly all nine of the nuclear states moved to modernize their existing nuclear arsenals and acquire new missiles in 2024.

Increasing geopolitical tensions have increased feelings of uncertainty and instability, which seems to have led countries to prioritize national security. The nuclear-armed states have made moves to expand the capabilities of their arsenals. SIPRI estimates that China now owns 600 nuclear warheads. Both the United Kingdom and France have ongoing programs to develop strategic weapons, including missiles and submarines. North Korea continues to expand its military nuclear program, accelerating the production of fissile material to make more nuclear warheads.

The threat of nuclear weapons seemed to loom over major events this year, even as their efficacy as a deterrent was thrown into question. As India and Pakistan engaged in aerial battles and strategic strikes in May, the conflict demonstrated to the world how close two nuclear powers could come to war.

Meanwhile, in the context of the ongoing war in Ukraine and the perceived threat from Russia, European nations, including France and the U.K., are moving to prioritize investments in defense, including deterrence. Germany, Denmark and Lithuania are among some of the countries that have also expressed interest in hosting nuclear weapons for the nuclear states.

William Potter, Director of the James Martin Center for Nonproliferation Studies, expressed concern over the dangers posed by nuclear weapons due to miscalculations and misperceptions at a time when “there is a total lack of trust, respect, and empathy among the nuclear weapons possessors.”

“The more nuclear weapons, the greater the risk of their inadvertent use, but even more dangerous is the absence of a political climate in which serious arms control and disarmament measures can be pursued,” Potter told IPS.

The safeguards for nuclear arms control are also being challenged. The NEW-Start treaty, the last remaining arms control treaty between the U.S. and Russia, is set to expire in February 2026, though both countries have considered voluntarily maintaining the limits on deployed strategic nuclear weapons for one year. Yet in this past week, that promise has been undercut by both parties.

At the same time, there are the continuous calls for nonproliferation and disarmament. Advocates from all over have raised awareness on the impacts of radiation on communities, on public safety and on the environment. The United Nations has platformed and rallied these advocates and has raised the alarm for disarmament since its official beginning on 24 October, 1945.

Amidst this, there is the fear of a new nuclear arms race. During the high-level meeting on the elimination of nuclear weapons in September this year, the UN’s Chef de Cabinet Courtenay Rattray, who delivered remarks on behalf of Secretary-General António Guterres, said that the world was “sleepwalking” into this new arms race, now defined by new technologies and new domains for conflict such as cyberspace. Rattney warned that “the risks of escalation and miscalculation are multiplying.”

So if the nuclear states are modernizing their arsenals, how do modern technologies fit in? Artificial intelligence (AI) is the latest frontier that countries are navigating and investing significant resources in to achieve progress. Given that, national and global regulations on the safe governance of AI are still nascent as countries still work to agree on universal agreements for the frameworks for the ethical applications of AI.

As it becomes increasingly sophisticated and more accessible, member states have been investing resources into incorporating AI in the military domain. Given that it does not fit neatly into pre-existing deterrence frameworks, this has also raised concerns over AI’s possible “destabilizing effects,” according to Wilfred Wan, Director of the SIPRI Weapons of Mass Destruction Programme.

It has prompted stakeholders to engage in serious negotiations on AI governance in the military domain, including guardrails to reduce the risk of escalation, Wan told IPS. At the multilateral level, he cites the example of the Blueprint for Action that came out of the second summit on Responsible AI in the Military Domain (REAIM) in 2024. It is a non-binding agreement among 61 countries, including nuclear powers like the U.S., the U.K., France and Pakistan, that provides a framework for the responsibility that parties need to take in integrating AI, and recognizing gaps that policymakers must take into account. There is also the UN General Assembly Resolution 79/239 on “[AI] in the military domain and its implications for international peace and security.”

“This is certainly not a substitute for disarmament progress, but in the current strategic context, it can help rebuild some of the trust and confidence necessary for revitalizing those efforts,” Wan said.

Researchers from SIPRI have found there are no governance frameworks specifically for the nuclear-AI nexus compared to those for conventional military systems. “In the nuclear context, discussions have largely centered on retaining human control in nuclear decision-making. This is an essential principle but does not address other ways in which AI integration can affect the environment in which nuclear decisions are made, directly or indirectly,” Wan explained.

“Absent a framework that addresses these aspects, including through regulatory and technical measures, there remains the risk of accelerated integration of AI among nuclear-armed states in a manner that destabilizes the security environment, threatens strategic stability, and impacts the risk of nuclear use.”

When assessing the existing approaches to the governance of military AI, it shows common areas of concern, such as raising awareness through multi-stakeholder engagement and preserving the capacity for human intervention, along with applying safety and security measures to mitigate escalation risks.

At this time, nuclear disarmament and nonproliferation are critical and may even provide insight into negotiating the governance of AI in nuclear forces. The approaches to fostering multi-stakeholder dialogue that include policymakers, non-nuclear states, experts and the private sector could similarly apply to discussions around AI in nuclear forces. Though it should be noted that their limited knowledge of nuclear force structures may constrain meaningful contributions to the debate. Nevertheless, their participation must be facilitated if nuclear parties truly value human control in this factor.

Nuclear and non-nuclear states must recommit to the anti-nuclear agreements, including the Nuclear Non-Proliferation Treaty, the Treaty for the Prohibition of Nuclear Weapons, and the Comprehensive Nuclear Test Ban Treaty. Potter stressed the importance of disarmament and nonproliferation education, particularly to empower future generations to “pursue creative ways to reduce pressing nuclear dangers.”

The UN can employ its influence in advancing disarmament efforts through dialogue and awareness efforts from the General Assembly and the Office of Disarmament Affairs (UN-ODA). The UN has also confirmed it will convene an independent scientific panel to assess the effects of nuclear warfare and an Expert Group on Nuclear-Free War Zones.

“Nuclear disarmament is more important today than ever before, but it is not simply a question of securing lower numbers of nuclear weapons,” Potter said. “At a time when the “nuclear taboo” has been eroded and discussions about the use of nuclear weapons have been normalized, it is vital that policymakers act boldly in a fashion commensurate with the threat.”
