At midnight last night, the New START treaty expired. For the first time since 1972, there are no limits on US-Russian nuclear arsenals. But here's what matters more than the legal technicality: the generation that remembers why arms control exists is retiring. The generation coming into power has no experiential memory of what uncontrolled nuclear competition looks like. We're about to find out what nuclear deterrence becomes when institutional memory disappears. The Epistemological Void For 54 years, nuclear stability rested on a foundation most people never thought about: both sides knew what the other had. Verification wasn't just inspections and data exchanges. It was shared reality . The basis for rational decision-making. The ground under mutual restraint. That ground just disappeared. Russia suspended verification in 2023. The US revoked inspector visas. COVID had already stopped inspections in 2020. Both sides believed the other was still complying with numerical limits, but nobody actually knew. Now even the limits don't exist. We've entered what intelligence analysts call an epistemological void —a space where neither side can actually know what the other is doing. Not speculation. Not belief. Actual knowledge based on verification. We've shifted from calculated deterrence (known capabilities, verified compliance, predictable behavior) to speculative deterrence (assumed capabilities, unverifiable claims, worst-case planning). When you can't see what the other side is doing, you prepare for the worst case. When both sides prepare for the worst case simultaneously, you get spirals. The Noetic Shift Something changed in collective human consciousness at midnight. For 54 years, we operated under the assumption that nuclear competition could be managed. That existential threats could be governed by mutual agreement. That the ultimate expression of power could be constrained voluntarily. That assumption just evaporated. The psychological shift is profound: From "nuclear weapons exist within a framework of control" To "nuclear weapons exist in a state of nature" How do strategists think differently when there are no limits? How do leaders calculate risk when there's no verification? How do publics perceive threat when there's no transparency? Why the Knowledge Transfer Isn't Automatic Yes, arms control expertise exists in think tanks, training programs, and government archives. The US and USSR built the original architecture from scratch in 1972—surely today's officials could rebuild if needed. But here's what documentation can't preserve: 1. Tacit Knowledge Loss : There's a difference between reading about verification negotiations and actually conducting them. The tacit expertise—knowing when to push, when to compromise, how to read counterpart flexibility—lives in practitioners, not documents. Michael Polanyi's insight applies: "We know more than we can tell." 2. Relationship Infrastructure Decay : Arms control worked partly because specific people knew specific counterparts. US negotiators who'd worked with Russian counterparts for decades. Military officers who'd conducted inspections and built personal trust. When those people retire, their relationships don't transfer to successors the way technical knowledge does. 3. Normalized Expectations Shift : The most insidious change isn't forgotten knowledge—it's shifted baselines. For the Cold War generation, normal meant nuclear competition with arms control. For the next generation, normal means the absence of treaties. The absence becomes normalized. That's a noetic shift documentation can't prevent. 4. Institutional Erosion Already Underway : The safeguard institutions are themselves weakening. Arms Control Association funding declining. State Department arms control bureaus downsized. Fewer graduate students specializing in nuclear issues. Russian-American academic exchanges frozen since 2022. The infrastructure you'd rebuild with is eroding. 5. Physical Infrastructure Takes Years : You can document how to conduct inspections, but the inspection protocols were embedded in treaty text (gone). Data exchange formats were standardized through practice (ended). Monitoring equipment was deployed and calibrated (dismantled). Access permissions were negotiated (expired). Rebuilding isn't just "remembering how"—it's re-negotiating access, re-deploying systems, re-establishing trust. That takes years even with perfect institutional memory. The Window The current generation of national security officials grew up post-Cold War. Within 5-10 years, no one in active decision-making roles will have direct experience with what we just lost. We have maybe 18 months before the decay becomes structural. Not because memory disappears in 18 months, but because relationship infrastructure decays, physical monitoring systems get reallocated, political windows close, and competitive dynamics normalize. The April-May 2026 NPT Review Conference is the next forcing function—a moment when nuclear weapons states must publicly account for their actions. But without the tacit expertise, relationship networks, and institutional capacity that took decades to build, I'm not confident we'll recognize the opportunity when we see it. The real danger isn't that someone deliberately starts an arms race. The danger is that a generation without experiential memory of uncontrolled nuclear competition stumbles into one—in the dark, without verification, preparing for worst-case scenarios they can't see—and wakes up one day in a situation their predecessors spent fifty years preventing. Not because they forgot what their predecessors knew. But because what their predecessors knew couldn't be fully transferred through documentation alone.
