Sharp, David

A 1970s submarine recovery operation by the C.I.A. is the subject of this documentary, which prioritizes the excitement of undercover work over any serious consideration of the agency’s legacy.The C.I.A. mission recalled in “Neither Confirm Nor Deny,” Philip Carter’s neat and steadily paced documentary, sounds like the stuff of a Tom Clancy Cold War thriller. In the film, C.I.A. veterans and journalists recount a 1974 U.S. operation to recover a Soviet nuclear submarine that had sunk in the Pacific six years earlier. It’s a high-risk mission made more suspenseful by technical challenges, the looming specter of Watergate and a need for secrecy in the face of scrutiny from Russia and the press.The story assembles before our eyes like an illustration in a manual for superspies. The goal: obtain valuable nuke data. The tool for the job: a big ship with the ability to snatch the sub and sneak it away to American shores. The cover story: an undersea mining operation fronted by Howard Hughes.David Sharp, who directed the mission and wrote a book about it, is the most prominently featured of the wonky talking heads here. He relates amazing details — like what the U.S. did with bodies of Soviet sailors that were discovered — in the understated manner of a kind science teacher. The Pulitzer-winning journalist Seymour M. Hersh, who wrote about the operation for The New York Times in the 1970s, offers a salty insider perspective.Almost in passing, we hear of the C.I.A.’s role in the bloody 1973 overthrow of the socialist government of Salvador Allende, who was then the democratically elected leader of Chile. In that light, the documentary, with its triumphant account, feels a little too selective in presenting the agency’s legacy, and its title — which seems to celebrate the government’s concealment of its actions from the public — comes across as misjudged.Neither Confirm Nor DenyNot rated.
