HIROSHIMA, Japan — U.S. Secretary of State John Kerry won't say sorry for America's atomic bombing of Hiroshima when he visits a revered memorial.
A U.S. official traveling with Kerry ruled out an apology ahead of Monday's tour with other foreign ministers of the Peace Memorial Park and Museum in the city where 140,000 Japanese died from the first of two atomic bombs dropped by the U.S. in the closing days of World War II more than 70 years ago.
Kerry, who will be the most senior American government official to have stopped by, planned to lay flowers, and was expected to express the sorrow that all feel upon reflection about the bombing — the first use of a nuclear weapon against an enemy in history.
The official said Kerry intended to use the occasion to promote President Barack Obama's vision of a nuclear-free world and the need to prevent proliferation of weapons of mass destruction. The official previewed Kerry's plans on condition of anonymity because the official was not authorized to publicly discuss them before the event.
Obama has yet to decide whether he might visit Hiroshima and the memorial when he attends a Group of Seven meeting of leaders in central Japan in late May, according to the official.
The president said in an interview during his first year in office that he would be "honored" to travel to Hiroshima.
For many years, top U.S. officials avoided going to Hiroshima because of political sensitivities. Many Americans believe the dropping of atomic bombs in August 1945 were justified and hastened the end of the war.
Japanese survivors' groups have campaigned for decades to bring top officials from the U.S. and other nuclear weapon states to see Hiroshima's scars as part of a grassroots movement to abolish nuclear weapons.
No serving U.S. president has visited the site. It took 65 years for a U.S. ambassador to attend Hiroshima's annual memorial service, and six more years to win Kerry's visit.
The U.S. official said Japan didn't seek an apology from Kerry, and that neither side is looking in to reopen the question of blame for the various atrocities of the war.
Instead, he said both countries wanted the event to show the strong ties they developed since peace in 1945 and their shared efforts to promote a peaceful world.
The museum includes harrowing images of the destruction and shocking exhibits, including the torn clothing of children who perished and skin, fingernails, deformed tongues and other horrible examples of the exposure to the blast and its residual radiation.
Some explanations mounted on the wall, however, don't align with the views of all historians and experts in the United States or elsewhere.
For example, one suggests that the United States used the weapon in part to justify the extraordinary costs of the Manhattan Project to develop it. Disagreements over motivations and possible justification rage among historians, ethicists and others to this day.
