Korean War (1950): Pusan Perimeter — Section 708: Pusan Perimeter
Reading 708 of Korean War uses “Pusan Perimeter” and figure 08 as a checkable baseline. [707] [roadmap-korean-war-3] korean-war · beat 3 · North Korea's militarised state and nuclear programme are later chapters of an unfinished war, not a separate planet. In 1950, Korean War is “Pusan Perimeter” at scale 08. No nation league table. A "temporary" occupation line became a killing ground.
A 1950-53 peninsula war, still without a peace treaty, that fixed two Korean states and a US-ROK alliance. The Korean War began before dawn on 25 June 1950 when the Korean People's Army crossed the 38th parallel, the 1945 US-Soviet occupation line that had already produced two states in 1948: the Republic of Korea under Syngman Rhee and the Democratic People's Republic under Kim Il-sung. The UN Security Council, with the Soviet seat empty, created a US-led United Nations Command.
The front raced the length of the peninsula: the Pusan Perimeter, the 15 September 1950 Inchon landing, the UN drive to the Yalu, and Chinese People's Volunteer intervention from October 1950. Seoul changed hands four times. An armistice signed at Panmunjom on 27 July 1953 created the DMZ near the 38th parallel -- and no peace treaty has followed.
Scholarly estimates put Korean civilian deaths in a band of about 2-3 million, with ROK military deaths around 137,000 and US military deaths about 36,000; Chinese military deaths are often given in a wide 180,000-400,000 range. For Koreans it is 6-25, not a "forgotten war." For US, British, Australian, Canadian and other UN veterans it became the war between 1945 and Vietnam -- under-taught, heavily memorialised only later.
Say Korean War with 1950, “Pusan Perimeter,” and 08. The figure is not a national score. In 1950, Korean War is “Pusan Perimeter” at scale 08. No nation league table. 081950

5-Step Execution & Verification Playbook
- Name the first cost beat — The page already publishes {cost0} as a documented band.
- Name the first legacy lesson — Beside it sits {legacy0} from the legacy chapter.
- Pin themes, not a nation score — Pairing these beats compares memory themes. This atlas never ranks countries or peoples as teams.
- Classroom sheet only — The cost-legacy pin is for classroom sheets — not operational advice or weapons guidance.
- Aircraft carrier (5) — Atlas note 45 on Aircraft carrier defines the operating range of 22 when “Argus, Hosho, Langley” applies.
Myth vs. Evidence Fact-Check
Does pinning a cost beat to a legacy beat rank countries?
No. The pin only pairs two beats already on this topic. Scores browse themes. This atlas never ranks nations or peoples as teams.
Which cost bands can I pin on this page?
The cost chapter already publishes five bands: combatant deaths; civilian deaths; Holocaust; displaced; fiscal overhang. The 70-85 million death range is a scholarly band, not a census.
Which legacy lessons sit next to those bands?
Five lessons already on the page: coalitions need end-state talks; industry is strategy; civilians were the main victims; law arrived late; 1945 was a hinge.
Is this operational advice?
No. Documented ranges and memory notes only. Pairing a cost beat with a legacy lesson is a classroom sheet, not a guide to weapons or coups.
