On Friday, U.S. President Barack Obama will become first American president to visit Japanese city of Hiroshima. The visit is huge event for both USA and Japan. Hiroshima is first city in the world to suffer from atomic weapons. The bomb that U.S. forces dropped on city in August of 1945 killed estimated 140,000 in that year. Many historians say it helped bring end to the Second World War. Others say it should never have happened. President Obama said his visit is to focus on future. An advisor to president said Mr Obama would not apologise for bombing. The advisor said Obama, "will offer forward-looking vision" that focuses on the shared future of the USA and Japan.
Barack Obama hinted in 2009 that he would one day like to visit Hiroshima. His trip to city has got many people in Japan and USA talking about bombs that fell on Hiroshima, and later Nagasaki, which killed so many people. Mr Obama said his visit would be time to think about how horrible war is and to remember terrible loss of life. He said he hoped his time in Hiroshima would remind people that war causes unnecessary death and that nuclear weapons should never be used again. He said: "Part of my goal is to recognise that innocent people caught in war can suffer tremendously." He added: "And that's not just thing of past. That is happening today in many parts of world."
