North Korea has embarked on a dramatic constitutional overhaul, fundamentally reshaping its national identity, power structure, and approach to the Korean Peninsula. The changes, ratified during the 15th Supreme People’s Assembly session in March 2026 and revealed in detail by multiple South Korean and international media outlets in early May, mark a historic departure from decades of doctrine. The new constitution not only cements Kim Jong-un’s grip as the country’s uncontested leader but also enshrines his exclusive authority over nuclear weapons—while formally abandoning the longstanding goal of Korean reunification.
According to Dong-A Ilbo, the revised constitution grants Kim Jong-un sole command over North Korea’s nuclear arsenal. For the first time, it also allows for the delegation of nuclear use authority to a designated state nuclear command body. This legal innovation creates a dual mechanism: even if Kim is incapacitated or killed in a so-called “decapitation strike,” the system enables an automatic nuclear retaliation. As experts noted, this “nuclear trigger” system is now given the weight of constitutional law, an extraordinary step not seen in other nuclear-armed states, which typically regulate such matters through lower-level statutes or military doctrine.
The significance of this move is hard to overstate. The constitutional embedding of an “automatic nuclear strike” policy is designed to deter foreign intervention by making clear that any attempt to remove Kim Jong-un could unleash devastating consequences. As Jung Sung-jang, deputy director of the Sejong Institute, told Dong-A Ilbo, “If a decapitation operation is carried out against the leader, it means an automatic nuclear retaliation will follow.” This codification, analysts say, is a stark warning to the United States and its allies.
But the nuclear provisions are only one side of the story. The amended constitution also introduces a new territorial clause, formally defining North Korea’s borders as abutting China and Russia to the north and South Korea to the south. Notably, the document refers to South Korea by its formal name, “Republic of Korea,” and omits any language about reunification or shared national identity. The omission of maritime boundary specifics—such as the contentious Northern Limit Line in the Yellow Sea—appears to be a calculated effort to avoid triggering immediate military disputes. As Professor Lee Jung-chul of Seoul National University explained at a government press briefing, “The absence of references to maritime boundaries suggests North Korea does not want to provoke new conflicts at this time.”
The constitutional changes were widely interpreted as the final abandonment of the North’s traditional “unification” policy, which had been a pillar of its ideology since the country’s founding in 1948. As News Space reported, all references to “homeland unification,” “socialist victory,” and “national reunification” have been erased from both the preamble and main text. In their place, the constitution now clearly delineates North and South Korea as separate, sovereign states—a concept known as the “two-state theory.” This shift, rooted in Kim Jong-un’s “hostile two states” policy first articulated in late 2023, represents a dramatic break with the past. For over 70 years, North Korea’s leadership—beginning with Kim Il-sung—had maintained the rhetoric of eventual reunification, even as political realities diverged.
“It’s a political and military turning point,” said Cho Han-bum, a senior research fellow at the Korea Institute for National Unification, as quoted by News Space. “The ‘hostile two states’ line Kim Jong-un ordered in late 2023 has now been completed in the constitution, marking the end of the North’s unification-oriented identity.”
The revised constitution also brings sweeping changes to the structure of state power. Kim Jong-un is now defined as the “head of state” for the first time, his authority elevated above that of the Supreme People’s Assembly chairman. He alone can appoint or dismiss key officials, including the premier and the assembly chairman, and he holds veto power over legislation. The preamble has been rewritten to remove references to Kim Il-sung and Kim Jong-il, instead highlighting Kim Jong-un’s own “People First” (Inmin Daejung Jeiljuui) ideology. This re-centering of the regime’s legitimacy around Kim Jong-un himself further consolidates his personal rule.
Other notable deletions include the removal of socialist slogans such as “tax-free country” and “free medical care,” reflecting a move away from promises of universal welfare that had little basis in reality. The constitution now includes a provision recognizing “heroes of overseas military operations” as a special protected group, a likely nod to North Korean fighters who died in the Russia-Ukraine conflict.
South Korean intelligence and academic experts, including Professor Lee Jung-chul, have emphasized the calculated nature of these changes. By removing overtly hostile language toward the South and omitting specific boundary disputes, North Korea appears to be seeking a degree of stability and international legitimacy, even as it entrenches the division of the peninsula. As Korea Report noted, the National Intelligence Service told lawmakers that “while the constitution clearly defines two states, the level of hostility has been significantly reduced.” The agency added that “the focus is on maintaining the status quo and managing the situation, rather than pursuing aggressive confrontation.”
Yet, the codification of Kim Jong-un’s nuclear monopoly raises serious questions for the future of diplomacy and security on the peninsula. The constitution now makes denuclearization negotiations even more fraught, as any concession on nuclear weapons would directly challenge the foundational legal framework of the North Korean state. As News Space observed, “Nuclear weapons are no longer just a military tool—they are the constitutional backbone of Kim Jong-un’s regime.”
Internationally, North Korea’s move sends a clear message. By institutionalizing its “responsible nuclear-armed state” status and making nuclear command a function of the supreme leader, Pyongyang is signaling that its deterrence posture is here to stay. The new constitution states the country will “strengthen nuclear capabilities to guarantee the nation’s right to survival and development, deter war, and safeguard regional and global peace and stability.”
For South Korea and its allies, the challenge is now compounded. The traditional framework for engagement—based on the prospect of eventual reconciliation and reunification—has been undermined. The North’s new legal order leaves little room for the rhetoric of “one people” or peaceful integration. Instead, the peninsula faces an era of institutionalized division, with two states staring warily across a heavily fortified border.
The world is left to grapple with a North Korea that has, through its own constitution, locked in permanent separation from the South and made its nuclear arsenal the centerpiece of its national identity. The question now is not just how to manage the risks of conflict, but whether any diplomatic path remains to reverse these momentous changes.
