The Stockholm International Peace Research Institute (SIPRI) warns that nuclear weapons are making a comeback as global peace remains elusive.
This trend signals a shift toward a new era of heightened nuclear risk. The reliance on nuclear deterrence suggests that diplomatic efforts to maintain peace are failing, leading states to prioritize military strength over arms reduction.
According to an analysis published in March 2024, governments are increasingly relying on nuclear deterrence to secure their interests [1]. This shift is particularly evident among nuclear-armed states, including the U.S., Russia, China, France, and the United Kingdom [2]. SIPRI said that the erosion of arms-control treaties and the perception that peace is unattainable are driving this expansion [2].
The global stockpile reached 13,080 warheads in 2023 [1]. This represents a two percent increase compared with 2022 [3]. The concentration of these weapons remains heavily skewed, with the U.S. and Russia holding about 90% of the world's nuclear warheads [4].
SIPRI said that the intensification of the global arms buildup is a response to a volatile international environment. As trust between major powers declines, the incentive to maintain or grow an arsenal as a deterrent increases, creating a cycle of escalation.
The report highlights that the current trajectory moves the world away from the goal of nuclear disarmament. With traditional diplomacy struggling to curb the buildup, the risk of accidental or intentional use of these weapons grows as more states integrate nuclear capabilities into their primary security strategies [1].
“Nuclear weapons are making a comeback as peace remains elusive”
The resurgence of nuclear deterrence indicates a breakdown in the post-Cold War security architecture. When nations prioritize nuclear expansion over arms-control treaties, the global safety net weakens, increasing the likelihood that regional conflicts could escalate into nuclear confrontations.
