We will prevent any attempt to spread right-wing extremist and revisionist worldviews at rallies". Subsequenty Austria formally banned the Bleiburg commemoration, and also banned, as a fascist symbol, the "chessboard" coat of arms of the NDH state, with the first white square, and removed it from the memorial at Bleiburg. Historiography Unlike many other operations of the Partisans, which have been described in detail, little has been written on operations in Slovenia near the Austrian border during the week of 7–15 May 1945. Postwar Yugoslav literature ascribed all human losses in May and June 1945 as military casualties in the final operations of the war. All opposing armies and political opponents were characterized by the Yugoslav historiography as traitors and collaborators. The events at Bleiburg were known as "final encirclement battles", "final military operations", and the "grand finale in Carinthia". The Bleiburg repatriations and their aftermath were first discussed in emigrant literature by anti-communists that managed to leave the country. One of the first book dealing with the subject was La Tragedia de Bleiburg, published by Croatian emigrants in Buenos Aires in 1963.The Minister and the Massacres, a 1986 book by Nikolai Tolstoy, further publicized the issue, but it made various dubious claims about the repatriations that were roundly criticized by various historians and authors, although it brought attention, more generally, to the persistent distortion of the story, and to the issue of historians trusting contemporary records and purported eyewitness.Rees, 2007. Croatian-American historian Jozo Tomasevich described the events: "The annihilation of most quisling troops captured at the end of the war – which is a fact – was an act of mass terror and brutal political surgery, similar to that practiced by the Ustašas and the Chetniks earlier in the war." Regarding Partisan treatment of Ustaše prisoners, Tomasevich notes: "We must now ask the really fundamental question, namely who was responsible for Bleiburg...The problem of Bleiburg obviously cannot be discussed in isolation, as Ustasha and pro-Ustasha writers regularly do. It is intimately related to the establishment and general policies of the NDH, to the Ustasha reign of terror against the Serbian population, to the Croatian state's determined alliance with Nazi Germany and with the Ustasha's final efforts to escape and ally with the West against the Communists. So we must conclude that the responsibility for Bleiburg was the collective responsibility of Pavelić and the Ustasha regime". British political scientist David
