President Barack Obama will become the first sitting U.S. president to visit Hiroshima, Japan. The White House announced Tuesday the president will visit the city where an American warplane dropped an atomic bomb near the end of World War II. The visit is scheduled for May 27. The president will not apologize for world’s first nuclear bombing, but will speak about the importance of limiting nuclear weapons, the White House said. Obama wants to highlight the “devastating effects of war,” said Benjamin Rhodes, Obama’s deputy national security adviser. Rhodes made his comment in a blog posted on Medium.com. The nuclear bombing of Hiroshima on August 6, 1945 killed about 140,000 people. The U.S. dropped a second nuclear bomb on the Japanese city of Nagasaki three days later, killing as many as 80,000 people. U.S. President Harry Truman said he ordered the bombings to bring a quicker end to World War II.
