Stalin was enraged by establishment of the NKOJ as an interim government and explicit repudiation of the government-in-exile in direct contradiction to explicit Soviet advice to avoid antagonising the exiled government and Peter II. Stalin was specifically worried about Tito's assumption of the presidency of the NKOJ and found his elevation to the rank of Marshal particularly provocative. He thought that this would signal to the Western Allies that the KPJ was actually fighting for a revolution. Stalin was further angered by the fact that he received no prior notice of the decisions.
