The United States Armed Forces and South Korean military concluded joint maneuvers six days ahead of schedule. North Korean military forces launched ten ballistic missiles toward the Sea of Japan during the previous reporting window. Ukrainian officials stated that North Korea deployed 400 drone operators to Kursk Region to support Russian troops. Military intelligence reports indicate North Korea delivered KN-30 ultra-heavy ballistic missiles to the Russian military.
United States Democratic lawmakers criticized the decision by Washington to scale back military exercises with South Korea. South Korean officials expressed concerns over potential diplomatic exclusion from direct United States negotiations with North Korea. Foreign Minister Wang Yi of China completed a diplomatic visit to Seoul. The Chinese Foreign Ministry declined to criticize North Korea for its recent missile testing.
North Korean state media attacked the Japanese Defense Ministry over proposed defense budget increases. Pyongyang characterized Japanese military spending as preparations for war. South Korea announced plans to dispatch its first commercial container ship through Arctic trade routes. North Korean military authorities discharged an officer after discovering his wife had family ties in China.
North Korea continues to leverage defense cooperation with Russia while reacting to regional military postures. Assessment: The theater will likely remain at elevated tension as North Korea maintains missile deployments and monitors future United States-South Korea defense decisions.

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 20/100 as of 1 January 1970 (coercive pressure), 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 20/100 — coercive pressure. 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. How the index works, and what it does not measure, is explained at wwiii.report/methodology.
How often is this updated?
Every day. The report is rebuilt from that day's reporting and the index re-judged from it, and a fall is published only once the evidence confirms it.

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.
Why it moved, under the chart, names what changed in the latest move: the day’s readings — strikes, casualties, talks — and, when the conflict’s stage was re-judged, what was graded differently and the events behind it. Open it for the detail.
Re-judged from open reporting by fixed formula — the model never picks a number — and a fall publishes only once the evidence confirms it. A dot on the line is a day the stage itself moved. How it is made →
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.
