Richard Sorge, his reports and the move of Soviet divisions from the east: E. Ziemke and M. Bauer, "Moscow to Stalingrad: Decision in the East", ch. III (U.S. Army Center of Military History, 1987); Wikipedia, "Richard Sorge". The quoted sentence of 14 September is an abridged English translation, with "Japan" added in brackets; the dated telegram is not shown as a facsimile. The telephone call between Stalin and Zhukov (around 19 November) and Zhukov's answer come from Zhukov's later memoirs, "by his later account"; Ziemke and Bauer only write that he "asked". The figure of eight armies and about 800,000 men is the count at the start of the counter-offensive (5-6 December), from a single source. The weight of Sorge's report in Stalin's decision to move divisions is debated: no number of divisions is given here.
The embassy front, the field telephone and the army markers are drawings, not photographs. The map is Natural Earth (public domain), turned a quarter turn (Moscow at the top, Tokyo at the bottom), with today's borders except the Soviet Union (merged); the markers are schematic and only Moscow, Tokyo and Japan are named.
