By following an international history approach, this article shows how legal concepts like extradition, repatriation or expulsion were, by the end of World War II, insufficiently developed to deal with the intricacies of prosecuting war criminals who had fled their countries of origins. Furthermore, this paper will underscore how those legal concepts became more about diplomacy than law, with the foreign-affairs branches of domestic governments interfering with matters that traditionally pertained to the judiciary power. The sensitivity of the Leon Degrelle case, the prominent position that he had had in Belgium, together with the need to readjust relations with the Francoist regime in the context of deteriorating relations between Western countries and the Soviet Union, forced the governments in London and Washington to tread very carefully in order to balance their national interests with the defence of justice and human rights. Ultimately, the pragmatic approach adopted by the Anglo-American authorities explains why Degrelle was not extradited to Belgium in 1945-1946.eninfo:eu-repo/semantics/openAccess5504.02 Historia contemporáneaartículoDegrellewar criminalsextraditionBritainUnited States1949-6540
