Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many people died?
Korean civilian deaths are often estimated at about 2-3 million. ROK military deaths are about 137,000; DPRK military deaths are less certain. US deaths are about 36,000. Chinese deaths are cited in a wide scholarly range, often 180,000-400,000. All figures are ranges, not precise censuses.
Why did the United Nations intervene?
The US took the war to the Security Council. Resolutions 83 and 84 (June-July 1950) recommended members assist the ROK. The Soviet Union was boycotting the Council over China's seat, so it did not veto. Sixteen countries sent combat forces; others sent medical units.
What was Inchon?
A surprise amphibious landing on 15 September 1950 at a port with extreme tides, designed to cut KPA supply lines to the Pusan Perimeter. It succeeded operationally and led to Seoul's recapture. It did not end the war, because the UN then drove north and China entered.
Why did China enter?
As UN forces approached the Yalu and the DPRK neared collapse, Mao's government -- after debate -- sent the People's Volunteer Army from mid-October 1950. Chinese accounts stress defending the border and supporting a socialist ally; UN accounts stress surprise and winter retreats from the north.
Who were the main commanders?
MacArthur (until relieved 11 April 1951), then Ridgway and Clark for the UN; Rhee and ROK chiefs including Chung Il-kwon and Paik Sun-yup; Kim Il-sung and Choi Yong-kun in the north; Peng Dehuai for Chinese forces. Truman's relief of MacArthur is a central civil-military episode.
Maps that only show the 38th parallel miss the 1950 race to Pusan and the Yalu. The DMZ is a 1953 artefact, slightly different from the 1945 line.
The UN Memorial Cemetery in Busan and the War Memorial of Korea are the two poles of public geography -- one coalition, one national.

Sayings
English-language "forgotten" talk should not be imported into Korean classrooms as if it were a fact about 6-25.
Veterans from Turkey to Ethiopia left small memorials; a full atlas of the war is multilingual.
