After decades of official denials from the Foreign Ministry, last year it was revealed that the Japanese government made a secret pact with the United States to allow the American military to bring nuclear weapons into Okinawa after the islands were returned to Japan in 1972.

One of the men who helped broker this deal was Kei Wakaizumi, who is the subject of the docudrama

"Sori no Misshi" ("The Prime Minister's Secret Envoy"; TBS, Mon., 9 p.m.). Wakaizumi was the main negotiator for the return of Okinawa in the 1960s, and afterward he was consumed by guilt, believing he had betrayed the people of Okinawa.
