In the summer of 2005, the Bush administration confronted a fresh wave of criticism over Guantánamo Bay.

To the public, these men are members of a familiar fraternity, presented tens of thousands of times on television and radio as “military analysts” whose long service has equipped them to give authoritative and unfettered judgments about the most pressing issues of the post-Sept. 11 world.

Hidden behind that appearance of objectivity, though, is a Pentagon information apparatus that has used those analysts in a campaign to generate favorable news coverage of the administration’s wartime performance, an examination by The New York Times has found.
