Shifting Sands: The Global Nuclear Weapons Landscape in 2023

The landscape of global nuclear armaments has undergone significant changes in 2023, marked by a deterioration in arms control treaties, enhanced nuclear proliferation risks, and an uptick in military capabilities by nuclear-armed states.

The Strategic Arms Reduction Treaty (New START), the last bastion of nuclear arms control between Russia and the United States, faced a critical juncture. Russian President Vladimir Putin's announcement that Moscow would suspend its involvement in the treaty underscored the escalating tensions and the fraying frameworks intended to curb nuclear expansion. The suspension, a response to what Russia perceived as U.S. non-compliance, highlighted the delicate balance of commitments holding mutual disarmament efforts in place.

As the standoff over New START persisted, the climate surrounding nuclear weapons utilization grew fraught. Comments from Russian public debate suggested an openness to limited nuclear use, a rhetoric shift indicative of the heightened nuclear alert level. This underscored a perilous period, with comparably high risks of nuclear conflict not witnessed since the Cold War era.

Compounding the strained relations, Russia's withdrawal from the Comprehensive Nuclear-Test-Ban Treaty (CTBT) reflected the deepening divide with Western nations, which sought to have Moscow reconsider its course. Yet, nuclear posturing was not an exclusively Russian affair. News of potential infrastructure investments by the U.S. in the UK for nuclear weapons deployment surfaced, pointing to shifts in NATO's nuclear strategies as well.

Against this backdrop of control framework collapses, the notion of nuclear sharing took on a new dimension. Russia embarked on an agreement to station tactical nuclear weapons in Belarus, a move closely mirroring U.S. nuclear sharing with European allies. This development heightened nuclear weapon profile in Eastern Europe, stoking concerns given the region's escalating hostilities.

Modernization of nuclear arsenals has become a priority for the United States, evidenced by the substantial budget allocation for nuclear enterprise modernization and advancements in the B61 nuclear gravity bomb. Russia, too, fortified strategic nuclear forces capabilities with the deployment of the Sarmat missile system.

China's actions in 2023 have added to the atmosphere of uncertainty and military expansion, with its growing arsenal attributed in part to concerns over U.S. missile defense systems. As countries maneuver for a more robust nuclear posture, the world faces a complex triad of nuclear-capable superpowers, complicating balance-of-power dynamics.

Iran's nuclear ambitions remained a focal point amidst these broader geopolitical shifts. Reports of Iran’s enrichment capabilities reaching near-weapons-grade fuel intensified the discourse on its potential nuclearization. Despite the uncertainties, hopes for a revised JCPOA linger, contingent on strategic economic and political negotiations.

The trajectory of the global nuclear weapons landscape in 2023 signals shifting tides in international relations and security strategies. The fading of pivotal arms control treaties and the progression toward more assertive nuclear postures by state actors paint a concerning picture, elevating the urgency for renewed diplomacy and effective arms management initiatives.
