One of the worst monsters the Nazis produced was Klaus Barbie, the 'Butcher of Lyon'.
In 1945 he was not executed but protected by British intelligence and the CIA. Why am I not surprised?
.............................
From 1945 to 1955, he was protected and employed by British, and then American, intelligence agents, who used his counter-insurgency skills to suppress the leftist resistance to the American and British occupations in Germany, France, Greece, and Italy.
In 1955, after the Americans and British were no longer in need of his services, Barbie, together with his wife and children, moved with American help to Bolivia. He lived in La Paz, Bolivia under the alias Klaus Altmann, where he became a drug lord and narcotrafficker. With Italian terrorist Stefano Delle Chiaie, he took part in the 'Cocaine Coup' of Luis GarcĂa Meza Tejada, when a notoriously corrupt military regime forced its way to power in Bolivia in 1980.
He was identified in Bolivia as early as 1971 by the Klarsfelds (Nazi hunters), but it was only on January 19, 1983, that a new moderate government arrested and deported him to France.
On July 4, 1987, Barbie was sentenced to life imprisonment for crimes against humanity, and died in prison of cancer four years later at the age of 77.
