In response to Molotov's summons, Tito dispatched Kardelj and Vladimir Bakarić to Moscow, where they joined Đilas. Stalin berated the Yugoslavs and Dimitrov for ignoring the USSR in the signing of the Bled Agreement and for Dimitrov's call to include Greece in a hypothetical federation with Bulgaria and Yugoslavia. He also demanded an end to the insurrection in Greece, arguing that any further support for the Communist guerrillas there might lead to a wider conflict with the United States and the British. By limiting his support to the DSE, Stalin adhered to the Percentages Agreement which placed Greece in the British sphere of influence.
