In August 2013, on the 60th anniversary of the coup, the US government released documents showing they were involved in staging the coup. The documents also describe the motivations behind the coup and the strategies used to stage it. The UK had sought to censor information regarding its role in the coup; a significant number of documents about the coup remained classified. The release of the declassified documents, which marked the first US official acknowledgement of its role, was seen as a goodwill gesture on the part of the Obama administration. According to Aljazeera, the deputy director of the National Security Archive, Malcolm Bryne, disclosed that the CIA documented the secret histories purposely for official use.
