A Defining Break from Seven Decades of Policy
North Korea has formally abandoned the founding dream that shaped its national identity for more than seven decades, rewriting its constitution to erase all references to reunification with South Korea and defining its territory as a separate state for the first time since its establishment in 1948. The sweeping revision, adopted during a March session of the Supreme People’s Assembly in Pyongyang, removes language that had anchored the nation’s political ethos since its founding, including pledges to pursue “independence, peaceful reunification, and great national unity.” The constitutional overhaul also strips away a previous commitment to “struggle to achieve national reunification,” a clause that had appeared in every iteration of the document since the country’s inception. References in the preamble to reunification-related achievements by state founder Kim Il-sung and former leader Kim Jong-il have also been deleted, signaling a generational break from the ideology that once justified the regime’s existence as the sole legitimate government of the entire Korean Peninsula.
North and South Korea remain technically at war because their 1950-53 conflict ended in an armistice rather than a peace treaty, a status that has allowed both sides to maintain large standing armies along one of the most heavily militarized frontiers on earth. The changes, revealed publicly in early May during a briefing at South Korea’s Unification Ministry, represent far more than a technical edit. Analysts across the region describe the move as a legal codification of leader Kim Jong-un’s increasingly explicit doctrine that North and South Korea are fundamentally “two hostile states” rather than one divided nation temporarily separated by geopolitical circumstance. For decades, both Seoul and Pyongyang maintained the position that unification remained an ultimate objective, even as they pursued radically different political and economic systems. By scrubbing this language from its highest law, Pyongyang appears to be declaring that the division is now permanent and that the two countries should interact as distinct sovereign entities. The move effectively erases one of the last legal vestiges of a shared national identity that both Koreas championed through decades of tension, dialogue, and intermittent conflict. For average observers, the change means that North Korea no longer even pays lip service to the idea of a unified Korean homeland, a concept that has shaped family reunions, diplomatic overtures, and propaganda narratives on both sides of the demilitarized zone for generations. The revision took more than two years to complete after Kim first ordered the change, reflecting the gravity of abandoning a principle that had shaped North Korean statecraft for generations.
Mapping the Constitutional Changes
The revised constitution introduces several structural changes that extend well beyond the removal of reunification rhetoric. Most striking is the addition of Article 2, which marks the first time North Korea has ever included a territorial clause in its constitution. The article defines the nation’s territory as land “bordering the People’s Republic of China and the Russian Federation to the north and the Republic of Korea to the south,” along with adjacent territorial waters and airspace. The clause states that North Korea “will never tolerate any infringement” of its territory, yet it conspicuously avoids specifying the exact location of the border with South Korea. It also makes no mention of the long disputed maritime boundaries in the Yellow Sea, particularly around the Northern Limit Line, a de facto sea border that has been the site of multiple deadly clashes over the past quarter century. The Northern Limit Line, drawn by the United Nations Command at the close of the Korean War, has never been accepted by Pyongyang, which argues that the boundary should be drawn farther south.
Lee Jung-chul, a professor at Seoul National University who analyzed the text at the Unification Ministry briefing, suggested the omission of a specific border between the two Koreas may be a deliberate effort by Pyongyang to avoid immediately creating a new source of friction. The ambiguous wording allows North Korea to assert territorial sovereignty without legally locking itself into a precise demarcation that could complicate future negotiations or military posturing. The revised document also elevates Kim Jong-un’s formal status by designating him, as chairman of the State Affairs Commission, as North Korea’s “head of state.” Previous constitutional language described the chairman merely as the country’s supreme leader who represents the state. The new text places the commission chairman above the Supreme People’s Assembly in the constitutional order of state institutions for the first time, further consolidating power in Kim’s hands.
In another major change, the constitution now explicitly states that command over North Korea’s nuclear forces rests with the State Affairs Commission chairman, formally granting Kim direct authority over the country’s expanding arsenal. A related defense clause describes North Korea as a “responsible nuclear weapons state” and commits to advancing nuclear weapons development to safeguard national survival, deter war, and protect regional stability. The revision also strips the Supreme People’s Assembly of its power to recall the president of the State Affairs Commission, effectively eliminating even the nominal legislative oversight that previously existed.
The Doctrine of Two Hostile States
The constitutional changes did not emerge in a vacuum. They represent the culmination of a dramatic policy pivot that Kim Jong-un began telegraphing in late 2023, when he started referring to South Korea as the North’s “main enemy” rather than a wayward brother state. In January 2024, Kim explicitly called for constitutional amendments that would define South Korea as the “primary foe and invariable principal enemy” and would formally state that North Korean territory was entirely separate from the South. He reinforced this stance in February, declaring that North Korea had absolutely no business dealing with South Korea and would permanently exclude South Korea from the category of compatriots. The following month, at a major party congress, he labelled Seoul the “most hostile state” in a policy address that set the tone for the constitutional revision.
These rhetorical shifts have been accompanied by tangible actions on the ground. During the administration of South Korea’s former conservative president Yoon Suk Yeol, North Korea demolished roads and railways that connected the two countries and erected what appeared to be physical barriers near the heavily fortified border. Seoul’s military reported in March that Pyongyang had resumed similar construction activity in the area. Kim also ordered the demolition of a major reunification monument in the North Korean capital, physically erasing a symbol that had stood for decades as a reminder of the purported goal of national unity. The constitutional revision now locks these attitudes into the country’s fundamental law, making it far more difficult for any future North Korean leadership to reverse course without facing a serious legitimacy crisis. By embedding the doctrine of two states in the constitution, Pyongyang has effectively closed the door on generations of policy built around the premise that the Korean Peninsula would eventually be made whole under a single government.
An Unexpected Omission
Despite the inflammatory rhetoric that preceded the revision, the final text of the constitution contains a notable surprise. It does not identify South Korea as a “primary foe,” contradicting widespread expectations that the document would mirror Kim Jong-un’s harsh public characterizations of Seoul. This omission has sparked considerable debate among analysts about Pyongyang’s true intentions. Some experts initially predicted the constitution would enshrine the “primary foe” label as a permanent legal category, creating an immutable barrier to future diplomacy. The fact that Kim’s government chose to omit the phrase suggests a calculated ambiguity that leaves room for interpretation. The discrepancy between Kim’s public speeches and the formal legal text highlights the complex balancing act Pyongyang faces as it attempts to solidify domestic ideology without prematurely closing off all diplomatic avenues or triggering an uncontrollable escalation.
Professor Yang Moo-jin of the University of North Korean Studies argued that the constitutional change sends an unambiguous message to Seoul.
“By deleting references related to unification, North Korea appears to have codified the message that it will no longer seek to claim South Korean territory,” he said. “In turn, Pyongyang expects the South not to infringe on the North’s territory. Leave us alone.”
Lee Jung-chul offered a somewhat more optimistic interpretation, viewing the revision as a potential foundation for peaceful coexistence between the two Korean states. He noted that the absence of explicitly hostile language toward Seoul, combined with the territorial clause, suggests Pyongyang may be attempting to project the image of a normal state that respects borders and seeks stability rather than perpetual confrontation. The decision to avoid specifying the border between the two Koreas or naming South Korea as an enemy in the constitution itself could reflect a strategic calculation to maintain flexibility while still embedding the doctrine of two states in the nation’s legal framework. Whether this represents a genuine step toward managed stability or simply a tactical pause in a broader campaign of hostility remains a central question for policymakers in Seoul, Washington, and Tokyo.
Seoul’s Calculated Response
South Korean officials have responded to the constitutional shift with a mixture of caution and continued outreach. The presidential office in Seoul stated that the government would conduct a comprehensive review of the revision’s details before formulating a full response, but emphasized that it would consistently pursue its peaceful coexistence policy for the Korean Peninsula. President Lee Jae-myung, who took office on a platform of engagement with the North, has repeatedly called for unconditional dialogue, saying the two countries are destined “to make the flowers of peace bloom.” In April, Lee vowed to act proactively to restore mutual trust in the hope that Pyongyang would respond in kind. His administration has resisted calls to adopt a confrontational stance, arguing that isolation and pressure have historically failed to alter North Korean behavior in any meaningful way. Unification Ministry officials in Seoul have indicated that they will study the revised document carefully to determine whether the omissions of hostile language represent a meaningful shift or merely a superficial adjustment designed to confuse international observers.
So far, those overtures have been met with silence from the North. Pyongyang has rebuffed repeated invitations to talks and has continued military activities that underscore its combative posture. In April alone, North Korea conducted four missile tests, the highest monthly total in more than two years, even as the constitutional text was being finalized. Kim has publicly vowed to continue expanding the country’s nuclear forces. The only modest sign of connection came with news that a North Korean women’s football team will travel to the South for a rare match later in May, though such sporting exchanges have historically done little to alter the broader political trajectory between the two governments. The gap between Seoul’s diplomatic optimism and Pyongyang’s military posturing continues to define a relationship that appears increasingly frozen in mutual suspicion.
Nuclear Forces and Expanding Alliances
The constitutional revision unfolds against a backdrop of deepening international alliances that are reshaping North Korea’s strategic position. Pyongyang has drawn much closer to Moscow since Russia launched its full scale invasion of Ukraine in 2022, forging a defense treaty in 2024 that calls for mutual military support in the event of either country being attacked. That same year, North Korea dispatched thousands of troops to Russia’s western Kursk region to assist in repelling Ukrainian offensives, marking the first time Pyongyang has committed ground forces to an overseas conflict in decades. These deployments have raised concerns in Seoul and Washington that Moscow may be providing advanced military technology or nuclear expertise to Pyongyang in exchange for such support. Senior Russian officials have made a series of prominent visits to North Korea, while Pyongyang has supplied artillery shells and other materiel to support Russia’s war effort.
China remains North Korea’s primary economic lifeline and diplomatic patron, but the Russia alignment offers Pyongyang an additional source of military technology and political backing on the world stage. South Korea’s Unification Ministry noted in April that the North Korean economy is showing signs of recovery, apparently fueled by deepening trade and diplomatic ties with both Russia and China. This economic stabilization, however modest, could provide Kim Jong-un with greater latitude to pursue his military modernization agenda without facing immediate domestic pressure. Analysts worry that a more economically stable North Korea, backed by two permanent members of the United Nations Security Council, will feel increasingly emboldened to ignore international sanctions and diplomatic pressure. The constitutional changes bolster this trajectory by formally designating the leader as head of state and granting him explicit command over nuclear forces, institutionalizing a system where military spending and weapons development take precedence over reconciliation or engagement with Seoul.
The Bottom Line

- A new territorial clause defines North Korea as bordering South Korea, China, and Russia, but avoids specifying exact land borders or disputed maritime boundaries
- Kim Jong-un is now formally designated as head of state and holds explicit constitutional command over the country’s nuclear forces
- The text notably omits language defining South Korea as a “primary foe” despite Kim’s previous public rhetoric
- South Korea maintains it will pursue a policy of peaceful coexistence while conducting a comprehensive review of the changes
- North Korea conducted four missile tests in April and continues deepening military ties with Russia, including troop deployments to support Moscow’s war in Ukraine
