North Korea has taken the extraordinary step of scrubbing all references to Korean reunification from its constitution, a revision that simultaneously defines the South as a sovereign neighbour and entrenches Kim Jong Un’s personal control over the country’s nuclear arsenal. The changes, adopted at a March session of the Supreme People’s Assembly and confirmed this week by Seoul’s Unification Ministry, mark the first time Pyongyang has included a territorial clause in its founding document. Article 2 now describes North Korean territory as abutting China and Russia to the north and “the Republic of Korea” to the south—language that, in a single stroke, discards seven decades of irredentist dogma.

The move completes a rhetorical arc Kim began in late 2023, when he declared the two Koreas “hostile states” and ordered the dismantling of agencies dedicated to unification. Analysts in Seoul note that the preamble has also been stripped of references to state founder Kim Il-sung and his son Kim Jong-il, along with the phrase “Kim Il-sung and Kim Jong-il Constitution.” In their place stand Kim Jong Un’s own governing doctrine, “the people-first principle,” and a new provision explicitly vesting command of nuclear forces in the chairman of the State Affairs Commission. The constitution now describes North Korea as “a responsible nuclear weapons state.”

South Korea’s presidential office responded with measured restraint, insisting it would continue its pursuit of peaceful coexistence despite what it called a “fundamental shift” in the North’s legal posture. Viewed from Washington, the revision raises immediate questions about denuclearisation talks; by formalising Kim’s nuclear command, Pyongyang has further entrenched a status quo the United States has long refused to recognise. European analysts, meanwhile, see a double-edged signal: the abandonment of unification rhetoric could reduce ideological friction along the border, yet the aggressive territorial definition and nuclear enshrinement heighten the risk of miscalculation.

The revision also deletes the earlier constitutional pledge to “struggle to achieve national reunification” and removes any mention of contested maritime boundaries such as the Northern Limit Line. What emerges is a legal framework designed for permanent division. Whether this hardens into a stable two-state reality or merely provides cover for future escalation depends on how the Kim dynasty chooses to wield its newly codified powers—and whether Seoul and its allies can craft a response that neither legitimises nor provokes the regime.
