Former Defense Secretary Robert Gates says he has no regrets about anything he wrote in his upcoming memoir that is critical of President Obama‘s handling of the war in Afghanistan, saying it’s an “honest account” of the administration’s foreign policy.

“Look, people gave me a lot of credit when I was in office for being blunt and candid about what I felt about things. I could hardly be any less in writing a book,” Gates told CBS in an interview that aired on its “Sunday Morning” program.
