Actually, it was Japan that attacked the US first. We retaliated by entering into WW2. To end the war with Japan, the US dropped atomic bombs on Hiroshima and Nagasaki. This caused Japan to surrender, marking the end of the war.
The Japanes attacked Pear Harbor without notice.
The two cities of Japan which were hit by the atomic bomb by America were "NAGASAKI" and "HIROSHIMA".
The US and Japan were at war, Japan having attacked the US, and declared war on America. Hiroshima was a military target, and relatively undamaged before the attack.
Harry S. Truman attacked Hiroshima because he needed a way to end the war quickly. The atomic bomb did just that.
It was an act of war- Japan having attacked the US, and formally declared war four and half years earlier.
Because the US and Japan were at war, japan having attacked the US in 1941, and had refused to surrender.
The war to which you referred was World War II. The dropping of the atomic bombs on Hiroshima and Nagasaki ended World War II.
