On 7 December 1943, Anthony Eden talked for the first time with Purić since the Tehran conference, where it was decided that Allies should support Yugoslav Partisans. After the meeting, Purić spoke with American ambassador Lincoln MacVeagh who later reported that Purić was extremely dissatisfied with the British decision to not allow his government to have direct communications with its people, which he called British failure to cooperate with the Yugoslav government. He also expressed concern that Allied military support to Partisans would cause conservative elements of the population to collaborate with the Germans. This confirmed suspicions of the Chetnik collaboration with the Germans, despite Purić likely not knowing about non-aggression pacts concluded between the Chetniks and Germans few weeks prior.
