Leaked cables show Japan nixed a presidential apology to Hiroshima and Nagasaki for using nukes to end the overseas contingency operation known as World War II. Will the next president apologize for the current one?
A heretofore secret cable dated Sept. 3, 2009, was recently released by WikiLeaks. Sent to Secretary of State Clinton, it reported Japan's Vice Foreign Minister Mitoji Yabunaka telling U.S. Ambassador John Roos that "the idea of President Obama visiting Hiroshima to apologize for the atomic bombing during World War II is a 'nonstarter.'"
The Japanese feared the apology would be exploited by anti-nuclear groups and those opposed to the defensive alliance between Japan and the U.S.
Whatever Tokyo's motive, Obama's motive was to once again apologize for defending freedom, this time for winning with devastating finality the war Japan started.
