After travelling to France for the purpose of carrying out the plan, Golubić was arrested by the French authorities and deported to Corfu, where he was asked to testify against Dimitrijević, who had since been detained on charges of plotting against the Serbian crown prince, Alexander.

Following the Axis invasion and occupation of the country, he was arrested by the Germans and eventually killed after refusing to disclose sensitive information under torture.

[8] Following the assassination of Archduke Franz Ferdinand on 28 June 1914 by the Young Bosnia member Gavrilo Princip, Golubić returned to Serbia, where he again joined the ranks of Tankosić's Chetniks.

Shortly thereafter, he was reassigned to the Bosnian Battalion of the Užice Army, which was under the command of General Ilija Gojković and whose chief of staff was Dragutin Dimitrijević, the head of Serbian military intelligence.

He returned to Serbia in September 1915, shortly before Austria-Hungary, Germany and Bulgaria's combined invasion of the country, which forced its military and much of its civilian population to retreat across Albania to the Greek island of Corfu.

[5] Upon returning to Serbia, which had in the meantime united with the other South Slavic lands in the western Balkans to form the Kingdom of Serbs, Croats and Slovenes, Golubić was immediately arrested and imprisoned inside the Rakovica Monastery.

He subsequently survived an assassination attempt, and after the Austrian authorities revoked his temporary residence visa, was forced to move to Prague.

[11] In one of his articles for La Fédération balkanique, Golubić claimed that Dimitrijević had organized and financed the assassination of Archduke Franz Ferdinand with the knowledge of the senior Russian diplomat Nicholas Hartwig, the Russian military attaché Viktor Alekseevich Artamonov, Serbian Prime Minister Nikola Pašić, and crown prince Alexander.

Describing the claims as unsubstantiated, Dedijer concludes that Golubić made these allegations "in a spirit of revenge" against Alexander, who had forced him into exile.

[12] In 1927, Golubić moved to Moscow, where he began working for the Joint State Political Directorate (OGPU), which was later renamed the People's Commissariat for Internal Affairs (NKVD).

[5] Alongside fellow Yugoslavs such as Vlajko Begović and Mirko Marković, Golubić played a key role in the Soviet Union's covert efforts to further the cause of the "world revolution".

[4] Golubić subsequently made contact with Dragiša Vasić and Mladen Žujović, who along with Stevan Moljević, would go on to become the chief advisers of Draža Mihailović, the leader of the wartime Yugoslav Army in the Fatherland.

Djilas, together with Aleksandar Ranković, another senior KPJ member, suspected Golubić himself of being a Trotskyite and feared that he was spreading misinformation regarding the Central Committee's activities to Moscow.

[14] On 5 June 1941, an explosion tore through a German ammunition dump in Smederevo, killing hundreds of residents and leaving much of the town in ruins.

[18] The following day, Golubić was arrested at the home of the lawyer Tihomir Višnjević in a joint action carried out by the Sicherheitsdienst (SD) and the Sicherheitspolizei (SiPo).

According to the war correspondent Sima Simić, who was detained alongside Golubić, the latter was so severely beaten that his face had turned blue and his urine was filled with blood.

[19] In July, after several weeks of torture, Golubić was taken to the Royal Garden in downtown Belgrade (modern-day Pioneers Park) and shot.
