Yongbyon Nuclear Expansion
International Atomic Energy Agency satellite analysis indicated North Korea constructed a second uranium enrichment facility at Yongbyon capable of housing 28 centrifuge cascades. The agency also observed expanded operations at the Kangson enrichment site near Pyongyang, maintaining remote monitoring due to the absence of IAEA inspectors since 2009.

Nuclear Policy Debates

The defense ministry statement rejected calls from the opposition People Power Party to pursue nuclear capabilities in response to North Korean missile activity.

Assessment
The Korean Peninsula experiences elevated friction driven by North Korean short-range missile launches, satellite-observed nuclear site expansions, and deepening military alignment with Moscow amid active South Korean border surveillance.
SCORE RATIONALE // North Korean short-range ballistic missile launches and satellite-verified nuclear enrichment facility expansion elevate regional friction above baseline levels.

COMMON QUESTIONS
Are North and South Korea at war?
No. The Korean War ended in an armistice in 1953, not a peace treaty, so the two Koreas are technically still at war and have not fought since. What continues is missile testing, exercises and periodic incidents along the border. The Korean War never legally ended: the 1953 armistice suspended it without a peace treaty. North Korea's only active-war role today is as a party on Russia's side in Ukraine. The index reads 17/100 as of 13 September 2026 (friction), on a scale where 50 and above is reserved for fighting actually under way.
How dangerous is the N. Korea and S. Korea situation right now?
The index reads 17/100 — friction. The scale is anchored on 22 historical episodes from 1914 to 2005, so the number means the same thing from one theater to the next. It is a measurement of what is reported, not a forecast.
How is the N. Korea and S. Korea risk index calculated?
By fixed formula from open-source reporting: events are extracted and graded by how well evidenced they are, scored across weighted factors, and the model never picks the number. The full construction — formulas, weights and the calibration set — is published at wwiii.report/methodology.
How often is this updated?
The reporting is reassessed daily. The index itself is recomputed on a rolling three-day cycle, and between recomputations it holds its last value rather than being re-judged without new evidence.

One 0–100 scale for the whole conflict. 0–49 is escalation before war; 50–100 is active war and how far it has gone.
50 is not a threshold the number can cross on its own. Which side a theater sits on is decided by whether verified belligerents are fighting there, so war onset always moves the score up across 50 — the number never declares a war by climbing.
It is a stage, not a probability: 42 is not a 42% chance of war. Below 50 it grades movement toward war, above 50 the war itself.
Recomputed every two days while a theater is at war and every five otherwise, from open reporting by fixed formula — the model never picks a number. Between recomputations the index holds its last value rather than being re-judged without new evidence. Full construction →
Direction — which way the week pushed. Severity — where the index sits. Connections — how much of the rest a shock here reaches. Cascade — that reach combined with how ready this theater is to go off.
The index reads the state of the conflict, not the volume of news. Each run grades the factors listed below against fixed rubrics, and the score follows by formula.
So a dramatic headline moves nothing unless it changes a grade. A theater already graded for recurring incursions absorbs one more without moving — it is priced in.
Open How this was measured for every grade, its movement since the last run, and the events behind it. Full construction →
A different measurement from the score above, from a different source. This line counts how much of the world's news reports conflict between these two states, against their own long-run normal: 100 is normal, 200 is twice the usual level.
It is computed mechanically from the GDELT Project's open event stream every 15 minutes and never touches the assessed index above — when both move together, that agreement is the signal. A day with too few events shows no reading rather than a guess. Click the chart for the full history.
Data: the GDELT Project.
Possible new links between this theater and the others, found automatically in machine-coded news: a state acting in both, alliance bridges, retaliation across them. Each entry leads with the headline that evidenced it.
Discovery, not verification. Nothing here changes any score. Nothing appears unless at least two independent sources from two different domains reported it within 72 hours, and only the editorial process can mark a connection verified.
