Abstract

Between 2017 and 2026, the United States government under Donald Trump orchestrated and advanced a systematic campaign of factually-false economic and security claims against its NATO allies, with America's closest ally and largest foreign market—Canada—as a primary target. This paper argues that this campaign is not a product of analytical error or political bluster but that the evidence is mounting for it being the intentional execution of a coherent operation whose mechanism of harm runs through the nuclear non-proliferation compact. States that voluntarily relinquished nuclear capability in exchange for the American security guarantee are being shown, persistently and publicly, that this guarantee is conditional and subject to revision at the whim of a single domestic actor in Washington. The 2026 Iran war, launched without allied consultation or congressional approval and without indication of the administration having a rational strategy of any kind, followed by demands that a systematically alienated alliance manage its consequences, and culminating in explicit threats to withdraw from NATO entirely—constitutes the proof of concept for this dynamic at operational scale. Ukraine's experience under the Budapest Memorandum supplies the completed case study. Intentional or otherwise, the sole coherent beneficiary of every stage of this process has been Putin's Kremlin. The ultimate risk is not bilateral damage to any particular alliance relationship. It is a global proliferation cascade and the manifold elevated potential for world and nuclear war. As the Trump administration's apparent contempt for its own alliance hardens from rhetorical posture into strategic record—normalizing authoritarian apologetics, dismantling the architecture of collective deterrence, and demonstrating that American nuclear protection is a revocable privilege subject to the discretion of one man rather than a binding collective obligation—member states will rationally recalculate the value of independent nuclear deterrence capability and seek to increase the size and efficacy of their own nuclear arsenals. This recalculation falls hardest on precisely those states that voluntarily chose complete denuclearization on faith in the American promise. The weakening of Article 5 credibility does not produce a more stable world. It produces one in which the American nuclear umbrella—the western world's central load-bearing structure underpinning the geopolitical stability, multilateral international cooperation, nuclear non-proliferation, and relative world peace since 1945—can no longer be trusted to open; an outcome which would at once embolden dictatorships everywhere while drastically weakening both the collective solidarity among democratic nations and the authoritarian fear of collective retaliation that has served as the free world's primary deterrent against both conventional invasion and nuclear coercion alike, upon which has stood the eight decades of relative peace between world powers since the Second World War.
