Wolfgram also criticized reporting on the alleged Operation Horseshoe, explaining that it was clear that there was coordinated action by Milošević's forces, but that NATO had tried to make it known that they were reacting to something that had been under way since November 1998.

Jing Ke showed in his study that "The Washington Times" and "The Washington Post" failed or ignored to report some of the crucial issues related to the Kosovo crisis, such as part of the Rambouillet Agreement, cluster-bombing of non-military targets and the bombing of the Radio Television of Serbia. Philip Hammond concluded that British media coverage of the NATO air campaign “encountered familiar problems of news management and propaganda” which were observed in post-Cold War conflict reporting.
