Victor Cha’s Cold Peace framework may dangerously misread North Korea by assuming long-term regime stability at a moment when the Kim regime’s internal fragility is rapidly deepening.
Key Insights
The Cold Peace framework rests on a dangerous assumption of regime stability: Much of the current debate assumes North Korea can be managed indefinitely as a stable nuclear state, while underestimating the regime’s growing internal fragility.
North Korea’s internal vulnerabilities are deepening: Rising elite distrust, military strain, ideological erosion from South Korean cultural influence, and Kim Jong Un’s unusually early succession push all point toward mounting instability within the regime.
A fragile nuclear regime may become more aggressive, not more stable: As internal pressures intensify, Pyongyang may increasingly rely on provocations, coercion, cyber operations, and strategic escalation for regime survival.
Kim Jong Un’s endgame goes beyond nuclear recognition: North Korea seeks to weaken the U.S.-South Korea alliance, reduce American influence, and expand North Korean and Chinese strategic influence on the Korean Peninsula.
Growing strains in the U.S.-South Korea alliance may create new strategic vulnerabilities: Political divisions and strategic divergence in Seoul could accelerate alliance fragmentation while advancing Pyongyang’s long-term objectives.
The United States and its allies should move beyond permanent Cold Peace management: Washington should pursue a Reagan-style strategy of sustained pressure while preparing strategically for a post-Kim North Korea.
In his recent Foreign Affairs article, “North Korea as It Is: The Case for a Cold Peace,” Victor Cha presents a sobering argument: the United States must abandon the illusion that North Korea will voluntarily denuclearize. Instead, Washington should begin treating North Korea as a de facto nuclear state and shift toward a long-term strategy centered on deterrence, arms control, and crisis management.
At first glance, the argument appears highly persuasive.
After more than three decades of failed negotiations, broken agreements, sanctions, and summit diplomacy, North Korea today possesses a far more advanced nuclear arsenal than many once imagined possible. Pyongyang has repeatedly demonstrated that it has no intention of surrendering its nuclear weapons, regardless of incentives or diplomatic engagement. Meanwhile, the risks of military confrontation have grown significantly as North Korea’s nuclear and missile capabilities continue to expand.
From this perspective, a “cold peace” may appear to be the most realistic option available. And to a certain extent, the framework captures part of reality. North Korea has become far more dangerous, and the failures of past denuclearization efforts cannot simply be ignored.
But this framework also contains a profound and dangerous blind spot.
The Wrong Assumption
The problem is not that the cold peace framework misunderstands North Korea’s nuclear program. The problem is that it fundamentally misreads the nature and trajectory of the regime itself.
The entire cold peace framework rests on a critical assumption: that the Kim regime will remain sufficiently stable, rational, and durable enough to be managed over the long term. Yet this assumption is becoming increasingly questionable. North Korea today is not merely a growing nuclear power. It is also a regime showing mounting signs of internal fragility.
Much of the mainstream debate surrounding North Korea remains overwhelmingly focused on external indicators: nuclear warheads, missile ranges, military cooperation with Russia, and strategic alignment with China. These factors are important. But they reveal only part of the picture. The deeper issue lies inside the regime itself.
The Blind Spot: North Korea’s Internal Fragility
Beneath the surface, North Korea faces growing structural pressures that are too often underestimated or ignored entirely: rising elite anxiety, internal distrust, deteriorating military loyalty, devastating troop losses in Russia, the continued spread of South Korean culture steadily eroding ideological control, and a dangerously premature succession effort centered on Kim Jong Un’s teenage daughter.
One of the clearest warning signs is Kim Jong Un’s unusually early effort to elevate his 13-year-old daughter, Kim Ju Ae, as a potential successor. In a hereditary dictatorship built on elite consensus and carefully managed legitimacy, accelerated succession planning is not a trivial development—especially when it involves a teenage girl in a deeply male-dominated political system. It may reflect deeper insecurity within the regime itself, including concerns surrounding Kim’s health and long-term stability.
Recent developments further reinforce these concerns. The large-scale reshuffling surrounding North Korea’s Ninth Party Congress in February 2026, along with changes among senior officials responsible for Kim Jong Un’s personal security, point to growing instability and distrust within the regime itself.
This is the central blind spot in the cold peace framework: it assumes regime continuity while underestimating regime fragility. And this distinction matters enormously.
Why a Fragile Nuclear Regime Becomes More Dangerous
A fragile authoritarian regime armed with nuclear weapons does not necessarily become more cautious. In many cases, it becomes more dangerous.
As internal instability grows, the regime may feel increasingly compelled to externalize pressure outward through military provocations, cyber operations, coercion, and strategic escalation. Aggression becomes not merely a tool of expansion, but also a mechanism of internal survival.
A cold peace is only sustainable when all sides are capable of sustaining long-term stability. But the Kim regime’s growing internal fragility may increasingly push it in the opposite direction.
This is why the central challenge facing the United States is no longer simply managing a nuclear North Korea. It is recognizing that the regime itself may already be becoming far more unstable than current policy assumptions acknowledge.
Misreading Kim Jong Un’s Endgame
This is particularly important when considering Kim Jong Un’s long-term strategic objectives.
North Korea’s ultimate goal is not simply to be accepted as a nuclear state. Its broader objective is to weaken American influence on the Korean Peninsula, undermine the U.S.-South Korea alliance, and gradually reshape the regional balance of power in its favor. Failing to understand this endgame creates enormous strategic risk.
Recognizing North Korea as a de facto nuclear state in pursuit of a cold peace would not stabilize the situation. It could instead embolden Pyongyang’s broader ambitions while accelerating doubts about American credibility and deterrence across the region.
Rather than moderating the regime, such an approach could unintentionally strengthen Kim Jong Un’s long-term strategic position.
The Weakening Alliance Environment
The assumption that stronger trilateral cooperation between the United States, South Korea, and Japan can naturally sustain such a framework is also far less certain than many analysts assume.
Political divisions inside South Korea continue to create vulnerabilities within the alliance structure itself. Under the Lee Jae-myung government, the U.S.-South Korea relationship has shown growing signs of strain and strategic divergence, amid broader debates over engagement with Pyongyang and relations with Beijing.
North Korea clearly understands these dynamics. Pyongyang’s long-term strategy has consistently sought to weaken the alliance structure surrounding the Korean Peninsula, reduce American influence in the region, and create political conditions favorable to its own strategic ambitions.
In this environment, a cold peace may not reduce instability. It could instead accelerate alliance fragmentation while creating greater strategic space for the expansion of North Korean and Chinese influence on the Korean Peninsula.
From Cold Peace to Post-Kim Preparation
The greatest strategic mistake Washington could make now is preparing indefinitely to manage a regime that may already be far deeper into systemic deterioration than conventional analysis assumes.
Certainly, the risks of military conflict must be taken seriously. North Korea’s nuclear arsenal poses a real danger to the United States and its allies. But a strategy shaped primarily by fear of escalation may ultimately embolden the Kim regime, creating even greater dangers over the long term.
History shows that authoritarian regimes often appear durable until internal cohesion begins to erode. In many cases, the decisive fracture emerges not simply from external pressure, but from growing distrust and fragmentation within the system itself. North Korea may prove no exception.
During the Cold War, President Ronald Reagan did not build American strategy around permanently managing the Soviet system as an immutable reality. He recognized its internal weaknesses, applied sustained pressure, strengthened alliances, and prepared strategically for the possibility of systemic transformation. He understood that lasting stability comes not from indefinitely accommodating hostile authoritarian regimes, but from creating the conditions for change.
Rather than settling for the dangerous illusion of a permanent cold peace, the United States and its allies should pursue a Reagan-style strategy of sustained pressure while preparing for a post-Kim North Korea.
The future of the Korean Peninsula will depend not on managing a fragile nuclear regime indefinitely, but on recognizing that its foundations are already rapidly eroding.
