“Peaceful reunification.” “Great national unity.” The clause pledging to “realise the unification of the motherland.” All of it — language present in some form in North Korea’s constitution since the state’s founding in 1948 — has been erased.

In its place: a new territorial clause. North Korea’s borders, per the revised Article 2, extend to land “bordering the People’s Republic of China and the Russian Federation to the north and the Republic of Korea to the south.” South Korea is named, formally, as a neighboring foreign state. The ambiguity that allowed both Koreas to claim eventual unity while pointing guns at each other across the DMZ has been stripped from Pyongyang’s highest law.

The revision, believed adopted at a March meeting of the Supreme People’s Assembly and reviewed by Reuters and Yonhap News Agency this week, represents the formal burial of a framework that existed since the 1953 armistice paused — but never ended — the Korean War.

What the new constitution says

The changes go beyond symbolism. For the first time, North Korea has defined its territory in constitutional law, including land, waters, and airspace — and stated it “will never tolerate any infringement” of its borders. Kim Jong Un is redesignated from “supreme leader who represents the state” to “head of state,” placing him above the legislature in the constitutional order. A new clause describes North Korea as a “responsible nuclear weapons state” and vests nuclear command authority in Kim personally as chairman of the State Affairs Commission. The revision also stripped the Supreme People’s Assembly of its power to recall the commission chairman, eliminating its nominal oversight role.

Notably absent: any specific reference to the inter-Korean border, including the disputed Northern Limit Line in the Yellow Sea. The text also stops short of labeling South Korea a “primary foe,” despite Kim calling for exactly that language in January 2024.

Professor Lee Jung-chul of Seoul National University told a briefing at the Unification Ministry that the border omission suggested Pyongyang wanted to avoid creating a new flashpoint even as it codifies its “two hostile states” doctrine. Lee characterized the revision positively, arguing it could lay the groundwork for “peaceful coexistence” between sovereign equals.

A shift locked into law

Kim began signaling this turn in late 2023, declaring Seoul the “main enemy” and ordering the demolition of a reunification monument in Pyongyang. The constitutional revision removes the diplomatic language that once provided off-ramps for de-escalation. South Korean President Lee Jae Myung has called for unconditional talks, saying the two countries are destined to “make the flowers of peace bloom.” Pyongyang has not responded.

Meanwhile, the military posture hardens. North Korea conducted four missile tests in April — the most in a single month in more than two years. The new constitutional enshrinement of nuclear command reinforces that Pyongyang views deterrence, not diplomacy, as its primary framework.

The Moscow factor

The rewrite does not exist in a vacuum. North Korea has drawn dramatically closer to Russia since Moscow’s 2022 invasion of Ukraine, sending thousands of troops to the Kursk region and supplying artillery for the front. A 2024 mutual defence treaty commits both countries to military support if attacked.

This alignment gives Pyongyang something rare: a major-power security guarantee beyond Beijing. China remains North Korea’s primary economic backer, but the Moscow relationship reduces the already slim leverage any external power might have over Pyongyang’s decisions. South Korea’s Unification Ministry noted in April that the North’s economy is showing recovery signs, partly through deepened trade with both Russia and China. A less vulnerable North Korea is a less negotiable one.

Frozen conflicts, hardened borders

The Korean constitutional shift fits a broader global pattern. From Transnistria to the Western Sahara to Kashmir, frozen conflicts have been hardening into permanent adversarial relationships. The language of “pending resolution” gives way to fortification and the normalization of division.

North Korea’s revision is among the most dramatic examples. A state founded on reclaiming the entire peninsula has now written its rival’s existence into its own borders — and written unity out of its charter. That does not make war more likely; clearer expectations on both sides may, paradoxically, reduce the risk. But it makes the kind of peace the peninsula once imagined structurally impossible. The doors to reconciliation have not been closed. They have been removed from the building.
