Nuclear Deterrence

The geopolitical landscape has entered a critical and highly volatile inflection point, defined by deepening transatlantic divisions and an unprecedented destabilisation of the global security architecture. The outbreak of intense military confrontation in the Middle East has accelerated this fragmentation, as the United States initiated pre-emptive operations against Iran, prompting Tehran to retaliate by closing the Strait of Hormuz. Given the Strait’s pivotal role as a strategic artery for global energy supplies, the administration of President Donald Trump called on European members of the North Atlantic Treaty Organization (NATO) to deploy naval units and provide military support to secure the passage. European capitals, however, rejected the request in a unified stance.   This refusal triggered a marked escalation in diplomatic tensions with the US administration. The European position rested on the absence of prior consultation and on a strategic assessment that classified the conflict as a discretionary war, falling outside the Alliance’s geographic remit and exceeding its defined defensive mandate. In response, the United States administration intensified its rhetoric, openly threatening withdrawal from NATO, describing the Alliance as a "paper tiger", and casting doubt on its military and political effectiveness.   This confrontation has transformed the prospect of a retrenchment in US security commitments from a theoretical possibility into a scenario under active strategic evaluation. Consequently, transatlantic relations have shifted from a framework of fixed commitments to one increasingly governed by transactional, interest-driven engagement. Assessing the likelihood of a US withdrawal, therefore, necessitates a comprehensive review of the governing international frameworks, the domestic constitutional constraints limiting executive authority, the military ramifications of withdrawal, and the potential future trajectories of Europe’s defence architecture.

Israel’s nuclear arsenal is one of the “worst-kept secrets” in the MENA region due to the strategic ambiguity regarding its existence. Currently, Israel is not a signatory to the Nuclear Proliferation Treaty and is allegedly the only state in the MENA region to possess nuclear warheads. It is estimated that Israel currently in possession of approximately 80 nuclear warheads that can be deployed through ballistic missiles or by aircraft. While this nuclear program is shrouded in ambiguity, there is a genuine fear that Israel can reveal the full extent of its nuclear capabilities in the form of the Samson Option, which can bare consequences for the nuclear taboo as well as adverse psychological effects for the MENA region and the world.

Amid the intensifying confrontation between Iran and Israel throughout 2025, the prospect of a direct strike against Israel’s Dimona nuclear facility has moved from a remote possibility to a plausible escalation scenario. As military operations increasingly target strategic infrastructure on both sides, the regional system faces the risk of a threshold breach—one that could trigger not only military and political consequences but also a multidimensional crisis involving radioactive contamination, mass displacement, and economic collapse across multiple states.   While Israel would undoubtedly bear the immediate brunt—facing mass civilian evacuations, irreversible environmental degradation in the Negev, and the paralysis of its agricultural and tourism sectors—the ripple effects would extend far beyond its borders.   Jordan’s border regions and agricultural zones in the Jordan Valley could face contamination and humanitarian strain, potentially requiring the evacuation of tens of thousands of people. Egypt’s Sinai Peninsula and northern Suez region could suffer fallout exposure, disrupting global shipping through the canal and threatening the Red Sea tourism corridor. Saudi Arabia’s northern provinces, including areas tied to its Vision 2030 megaprojects, could face both environmental and demographic disruption.
