Japanese refused to surrender
By this point in the Pacific War, the US forces, with the help from its Allies, had regained most of the territories that Japan had invaded such as the Philipine Islands,Borneo and Burma
In response to Japan's refusal to surrender, the US forces attacked the Japanese home islands, such as Iwo Jima and Okinawa
The Japanese resisted fiercely and over 100 000 soldiers on both sides were killed
In an attempt to force the Japanese to surrender, the US air force intensified its bombing on the Japanese mainland
But still the Japanese would not surrender
The USA said it had identified Hiroshima, as a city that had many weapons factories
In addition, the US dropped a second atomic bomb on Nagasaki - a city the USA identified as having dockyards that built warships for Japan - on 9 August
