return he wrote a detailed report on the matter which, by some opinions, greatly affected and shaped firm official Yugoslav view on the whole situation. Parts of his memories and thoughts on the circumstances later will be published under the name Seven Days in Budapest. In late 1956 Ćosić was chosen to participate in the formation of a new program for the Communist Party. Tito and Edvard Kardelj both picked Ćosić to sit on the committee along with other prominent Yugoslav communists. When it was completed in 1958, Ćosić had claimed that he himself wrote parts of it, including the chapter on "Social-Economic System". Ćosić was concerned about the program's neglect of culture and pressed for more attention to be given to the role of culture in socialism but Kardelj, who was the final arbiter, was unresponsive to these concerns.

Nevertheless, actual political measures undertaken after 1962 actually followed the positions voiced by Pirjevec and the Slovenian Communist leadership. Precipitated by a slow economy, opposing sides came to use Ćosić and Pirjevec as proxies in their battles for a competing vision of Yugoslavia in the early to mid-1960s. As the government gradually decentralized administration of Yugoslavia after 1963, Ćosić grew convinced that the Serbian population of the state was imperiled. In May 1968, he gave a celebrated speech to the Fourteenth Plenum of the Central Committee of the Serbian League of Communists, in which he condemned the then-current nationalities policy in Yugoslavia. He was
