On December 22, 2015, the United States released declassified lists of targets for a massive nuclear strike on the USSR, Eastern Bloc countries, and China.

The secret document, compiled in 1956, spans 800 pages and reveals strategic points for a potential U.S. nuclear attack in the event of war with the USSR.

The list includes 179 targets in Moscow, 145 in Leningrad, and 91 in East Berlin, Beijing, and Warsaw.

The most shocking entry in this list is point No. 275—“population”: alongside military and industrial facilities, civilian populations in residential areas were also marked for elimination.
