Nuclear fears surge: europe rethinks deterrence amidst trump’s threats

The specter of renewed global conflict is rising, fueled by escalating tensions in Iran and a shifting landscape of international security. A confluence of factors – Trump’s unpredictable pronouncements, Russia’s aggressive posture, and China’s burgeoning nuclear capabilities – is prompting a re-evaluation of deterrence strategies, with potentially destabilizing consequences.

Europe's nuclear pivot: a response to uncertainty

For decades, nations like Germany and Poland have relied on the U.S. nuclear umbrella. Now, emboldened by French proposals and unnerved by Trump’s threats regarding Greenland, they’re exploring bolstering Europe’s own strategic deterrence capabilities. This represents a significant departure from established norms, a tacit acknowledgment that the traditional security architecture is fraying.

But the shift isn’t confined to Europe. China and Russia are issuing stark warnings against proliferation, particularly in Japan and South Korea – nations increasingly contemplating their own nuclear options as U.S. commitment becomes a point of contention. The possibility of the U.S. resuming atomic bomb testing, spurred by a Trump executive order, further complicates an already volatile situation.

The crumbling arms control system

The foundations of the post-Cold War arms control system – painstakingly constructed after the world stared into the abyss of mutual assured destruction – are now demonstrably cracking. The 1987 Reagan-Gorbachev treaty eliminating intermediate-range missiles was a watershed moment, followed by subsequent reductions under the New START treaty. These agreements, once considered bedrock, are now strained by deteriorating U.S.-Russia relations and China's decision to pursue its nuclear ambitions outside of bilateral agreements.

The grim reality is this: conventional missiles regularly impact cities across Europe and the Middle East, while the remaining arms control treaties face an uncertain future. Next month's United Nations review of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) looms large, offering a potentially fraught opportunity for reassessment – or further disintegration.

A cascade of proliferation?

The danger isn't merely the existence of nuclear weapons in nine recognized states. More than twenty nations possess the industrial base and technical expertise to develop them. Just 25 kilograms of highly enriched uranium or 8 kilograms of plutonium are enough to construct a weapon capable of devastating a city. This stark fact, once relegated to theoretical discussions, is now being seriously considered by countries that have historically pledged never to pursue nuclear arsenals, driven by a growing belief that disarmament leaves them vulnerable.

Rafael Mariano Grossi, Director General of the IAEA, cautions that “a greater number of nuclear weapons in more countries will not make the world safer, but the opposite.” Experts warn that the more nations possess nuclear capabilities, the more difficult it becomes to control their use, exponentially increasing the risk of global catastrophe. Libya, Ukraine, and now Iran serve as cautionary tales – demonstrating that nuclear weapons don’t guarantee immunity but sharply elevate the stakes of conflict. The term “proliferation cascade” – a chain reaction in the Middle East and East Asia – is no longer academic.

Hypocrisy and shifting alliances

The U.S. stance on Iran stands in stark contrast to its recent overtures to Saudi Arabia. Just last month, the administration advocated for sharing sensitive nuclear Technology with Riyadh, including potential cooperation on uranium enrichment and plutonium reprocessing – a move critics have labelled “hypocritical.” While the U.S. accuses Iran of pursuing nuclear weapons, it simultaneously facilitates the expansion of Saudi Arabia’s nuclear capabilities. The contrast is jarring, undermining the credibility of U.S. non-proliferation efforts.

The erosion of trust in the U.S. extends beyond the Middle East. Remember Trump’s aborted attempts to negotiate with Kim Jong-un, culminating in failed summits in Singapore and Hanoi? Now, even Japan, scarred by the atomic bombings of Hiroshima and Nagasaki, is witnessing a resurgence in calls for a domestically developed nuclear deterrent, fueled by rising tensions with China and waning confidence in U.S. commitment.

As Jeffrey Lewis, Director of the East Asia Nonproliferation Program, bluntly puts it:
