The figures, side by side

Each figure is the same observation, with the same source, as on the two dossiers. Every value shows the year it was observed — vintages differ by indicator and nation. A “—” is an absence in the source data, never a zero. Metric names link to the world ranking; values open the figure on its own dossier.

  8. Night of 10-11 August 1945

    Rusk and Bonesteel propose the 38th parallel

    During an overnight meeting in John McCloy's Pentagon office, US Army officers Dean Rusk and Charles Bonesteel are asked to retire to an adjoining room and propose where US forces should accept Japan's surrender in Korea. They recommend the 38th parallel to include Seoul in the American area, though it lay further north than US forces could reach if the Soviet Union disagreed (Rusk's own later account, 1950).

    Stalin does not object to General Order No. 1

In his 16 August reply Stalin writes that he has no objection in principle to the order, asking only for changes concerning the Kuril Islands and northern Hokkaido; Rusk later recalled being surprised that the Soviet Union accepted the parallel.
