Wedoany.com Report-Oct 31 , Following Israel’s October 26, 2024, attack on Iranian energy facilities, Iran vowed to respond with “all available tools,” sparking fears it could soon produce a nuclear weapon to pose a more credible threat. The country’s breakout time—the period required to develop a nuclear bomb—is now estimated in weeks, and Tehran could proceed with weaponisation if it believes itself or its proxies are losing ground to Israel.

Iran isn’t the only nation advancing its nuclear capabilities in recent years. In 2019, the U.S. withdrew from the Intermediate-Range Nuclear Forces Treaty (INF), which banned intermediate-range land-based missiles, citing alleged Russian violations and China’s non-involvement. The U.S. is also modernizing its nuclear arsenal, with plans to deploy nuclear weapons in more NATO states and proposals to extend its nuclear umbrella to Taiwan.

Russia, too, has intensified its nuclear posture, expanding nuclear military drills and updating its nuclear policies on first use. In 2023, it suspended participation in the New START missile treaty, which limited U.S. and Russian deployed nuclear weapons and delivery systems, and stationed nuclear weapons in Belarus in 2024. Russia and China have also deepened their nuclear cooperation, setting China on a path to rapidly expand its arsenal, as nuclear security collaboration with the U.S. has steadily diminished over the past decade.

The breakdown of diplomacy and rising nuclear brinkmanship among major powers are heightening nuclear insecurity among themselves, but also risk spurring a new nuclear arms race. Alongside Iran, numerous countries maintain the technological infrastructure to quickly build nuclear weapons. Preventing nuclear proliferation would require significant collaboration among major powers, a prospect currently out of reach.

However, the Non-Proliferation Treaty (NPT), enacted in 1968 to curb nuclear spread, led many countries to abandon or dismantle their programs. After the end of the Cold War and under Western pressure, Iraq ended its nuclear program in 1991, and South Africa, in a historic move, voluntarily dismantled its arsenal in 1994. Kazakhstan, Belarus, and Ukraine relinquished the nuclear weapons they inherited after the collapse of the Soviet Union by 1996, securing international security assurances in exchange.

Nuclear proliferation appeared to be a waning concern, but cracks soon appeared in the non-proliferation framework. Pakistan conducted its first nuclear test in 1998, followed by North Korea in 2006, bringing the count of nuclear-armed states to nine. Since then, Iran’s nuclear weapons program, initiated in the 1980s, has been a major target of Western non-proliferation efforts.

Iran has a strong reason to persist. Ukraine’s former nuclear arsenal might have deterred Russian aggression in 2014 and 2022, while Libya’s Muammar Gaddafi, who dismantled the country’s nuclear program in 2003, was overthrown by a NATO-led coalition and local forces in 2011. If Iran achieves a functional nuclear weapon, it will lose the ability to leverage its nuclear program as a bargaining chip to extract concessions in negotiations. While a nuclear weapon will represent a new form of leverage, it would also intensify pressure from the U.S. and Israel, both of whom have engaged in a cycle of escalating, sometimes deadly, confrontations with Iran and its proxies over the past few years.

An Iranian nuclear arsenal could also ignite a nuclear arms race in the Middle East. Its relations with Saudi Arabia remain delicate, despite the 2023 détente brokered by China, and Saudi officials have previously indicated they would obtain their own nuclear weapon if Iran acquired them. Saudi Arabia gave significant backing to Pakistan’s nuclear weapons program, with the understanding that Pakistan could extend its nuclear umbrella to Saudi Arabia, or even supply the latter with one upon request.

Turkey, which hosts U.S. nuclear weapons through NATO’s sharing program, signaled a policy shift in 2019 when President Erdogan criticized foreign powers for dictating Turkey’s ability to build its own nuclear weapon. Turkey’s growing partnership with Russia in nuclear energy could meanwhile provide it with the enrichment expertise needed to eventually do so.

Middle Eastern tensions are not the only force threatening non-proliferation. Japan’s renewed friction with China, North Korea, and Russia over the past decade has intensified Tokyo’s focus on nuclear readiness. Although Japan developed a nuclear program in the 1940s, it was dismantled after World War II. Japan’s breakout period, however, remains measured in months, but public support for nuclear weapons remains low, given the legacy of Hiroshima and Nagasaki, where nuclear bombings in 1945 killed more than 200,000 people.
