Kou Voravong
The political crisis caused by his assassination, barely two months after the Geneva Agreements which prepared to restore peace in Indochina, contributed to bring down the current neutralist government (pro-French) which was replaced by a progressive one (pro-American) in extremely tense atmosphere of the Cold War between Russia and the United States. From 1955 indeed, the political history of this small landlocked country fell trapped inexorably in the ideological confrontation between the capitalist United States and the communist Soviet Union, annihilating any hope of national unification.
Igor Korobov
Korobov died on 21 November 2018, "after a long and serious illness", according to sources in the Russian defence ministry cited by official news agencies. Korobov's death was a few months after the badly bungled poisoning of Sergei and Yulia Skripal, widely attributed to Korobov's GRU. GRU defector Viktor Suvorov has no direct information, but said "my spy instinct tells me that Korobov was murdered. Everyone sitting inside GRU would understand this, 125%." Korobov would have been killed to eliminate a witness who might defect.
