A simplified map of the Cold War alliances between 30 April and 24 June 1975. The Soviet and Chinese blocs are grouped together as one for illustrative purposes, but note that historically they were not allied during the time represented. The grey region does not represent an alliance, but rather encompasses all countries that were not aligned with the Soviet Union, the USA, or China. This map is based on File:First second third worlds map.svg, but it is modified to display a grouping of countries that is verifiable and accurately reflects the caption of Three Worlds.

Rationale:
The map is dated immediately after the Fall of Saigon. The next change to the map would be the independence of Mozambique from Portugal on 25 June 1975.
