After Vergès's return to normal life he resumed his legal practice, defending Georges Ibrahim Abdallah, convicted of terrorism, and Nazi war Criminal Klaus Barbie. The thrust of his defence in the latter case was that Barbie was being singled out for prosecution while the French state conveniently ignored other cases that qualified as crimes against humanity. Vergès adopted a tu quoque defense, asking the judges "is a crime against humanity is to be defined as only one of Nazis against the Jews or if it applies to more seriously crimes...the crimes of imperialists against people struggling for their independence?", going on to say there was nothing his client did against the Resistance that was not done by "certain French officers in Algeria" whom Vergès noted could not be prosecuted because of de Gaulle's amnesty of 1962. As such, Vergès argued that the republic had no right to convict Barbie of anything given that French officers like the war hero General Jacques Massu had also engaged in torture and extrajudicial executions during the fight against the FLN. Besides for his tu quoque defense of arguing that French actions in the Algerian War were no different from Barbie's, Vergès spent much time attempting to prove Jean Moulin had been betrayed by either the Communists, the Gaullists, or both, which led him to argue Barbie was less culpable than those who had betrayed Moulin. Vergès claimed Moulin's colleagues were "playing a double game" and all those in the Resistance "whether they were anti-Gaullists or anti-Communists forgot their duty to the Resistance because of partisan political passions". At one point, Vergès claimed that Moulin had actually wanted to be tortured to death and tipped off Barbie himself. Reviewing the film Hôtel Terminus: The Life and Times of Klaus Barbie, the film critic David Denby wrote the climax of the film was when the French filmmaker Marcel Ophüls pressed the "despicable" Vergès during an interview about his defense of Barbie, whom Denby wrote "...persists in pretending that Barbie is a victim of some sort".
