DMZ Blast Investigation
South Korean troops and United Nations Command Military Armistice Commission personnel opened access routes in the western Demilitarized Zone to investigate the September 21 mine explosion that injured three South Korean officers. Subsequent soldier statements identified additional unexploded ordnance near the site, while South Korean opposition politicians alleged the Lee Jae Myung administration delayed the probe to avoid straining inter-Korean relations.

Air Defense Modernization

The induction establishes independent domestic manufacturing capability for advanced combat aircraft intended to bolster frontline territorial air defense.

Assessment
The theater remains under routine armistice conditions and reciprocal defense posturing, with recent activity confined to border investigative operations and routine military procurement.
BOTTOM LINE // The Korean Peninsula remains under routine armistice friction as South Korean and United Nations Command personnel conduct joint DMZ mine blast surveys.
RAND analysts project that the United States Congress is unlikely to approve large-scale offshore construction of combat-relevant naval vessels in South Korea. Consequently, bilateral maritime industrial cooperation will depend on long-term supplier localization, legal tech safeguards, and specialized labor visa agreements.

North Korean forces fired a barrage of ten suspected ballistic missiles into the sea shortly after the United States and South Korea ended their joint Ulchi exercise early. Officials from Seoul, Washington, and Tokyo convened to coordinate responses to the launches.
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 19.4/100 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 19.4/100 — 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.
