here. Star Trek mirrored the collapse of the Soviet Union with the collapse of the Klingon Empire whereas Poul Anderson's Terran Empire and Merseian Roidhunate are both still in place at the end of the last novel to be set during the Flandry period of the Technic History. However, Dominic Flandry lives long and reminisces about earlier stages of that conflict.
I will shortly read le Carre's A Legacy Of Spies, the recent sequel to his Cold War classic, The Spy Who Came In From The Cold, and will no doubt make some comparisons with Flandry. See:
