Obama to Make History with Hiroshima Visit, as U.S. Quietly Upgrades Nuclear Arsenal

President Obama will become the first serving U.S. president to visit Hiroshima, Japan, later this month. The White House said Obama will not apologize for dropping an atomic bomb on the city toward the end of World War II. The attack on August 6, 1945, caused massive and widespread destruction. Shock waves, radiation and heat rays took the lives of some 140,000 people. Three days later, the U.S. dropped a second atomic bomb on Nagasaki, killing another 74,000 people. President Obama is expected to tour the site of the world’s first nuclear attack with Japan’s prime minister, Shinzo Abe. Obama’s communications adviser Ben Rhodes said that Obama’s time in Hiroshima will "reaffirm America’s longstanding commitment -- and the president’s personal commitment -- to pursue the peace and security of a world without nuclear weapons." Obama’s visit comes as a report by the Alliance for Nuclear Accountability has revealed the United States has been quietly upgrading its nuclear arsenal to create smaller, more precise nuclear bombs as part of a massive effort that will cost up to $1 trillion over three decades.
