“We believed that the information we had, the intelligence we had, was such that Sgt. Bergdahl’s safety and health were in jeopardy,” Mr. Hagel said. “In particular his health was deteriorating. It was our judgment that if we could find an opening and move very quickly, we needed to get him out of there, essentially to save his life,” he added.
“The first focus is on his health and getting the medical attention he needs,” Mr. Hagel said.
