The Persistent Shadow of Nuclear Escalation

Despite decades of viewing nuclear weapons as "unusable" relics of the Cold War, the war in Ukraine has re-established them as central pillars of modern conflict. The research highlights a critical moment in late 2022 when the potential collapse of Russian lines in Kharkiv and Kherson led U.S. intelligence to estimate the risk of nuclear use as a "coin flip." While the frontline eventually stabilized, the lesson remains: authoritarian leaders may view nuclear deployment as a viable tool if they face total military defeat. This reality forces a return to Cold War-style risk management, where every conventional move must be weighed against the fragile norm of nuclear non-use.

The Reality of Protracted Attrition

Contrary to initial projections of a "short and devastating" campaign, the Ukraine war has demonstrated that nuclear-armed states can engage in long-term, high-intensity conventional warfare without crossing the atomic threshold. This "protraction" is often the indirect result of careful escalation management; by intentionally limiting the scope of the war to avoid a global catastrophe, both sides inadvertently create a stalemate of attrition. For the United States, this necessitates a massive reinvestment in the defense industrial base to sustain long-term stockpiles of munitions and air defenses, moving away from a military optimized solely for short, decisive engagements.

Tacit Bargaining and the ‘Salami Slicing’ Strategy

Escalation thresholds are not fixed; they are negotiated through active probing and "salami slicing." Throughout the conflict, the West gradually increased its support, moving from small arms to tanks, then to long-range ATACMS, and eventually enabling strikes within Russian territory. By making incremental changes rather than dramatic jumps, the U.S. and its allies effectively eroded Russia’s purported "red lines" without triggering a direct kinetic response against NATO. This process of tacit bargaining suggests that future victory will depend on a nation's ability to signal restraint while simultaneously escalating in ways that paralyze the adversary’s decision-making.
