Why did the united states seize pacific islands during world war ii?

The correct answer is To establish military bases for use in further attacks

The conflict in the Pacific continued until September 1945, when Japan surrendered. Beginning in the second half of 1942, the United States began to win all major battles. The great battles after 1942 were:

Battle of Midway (June 1942) : Japanese attempt to invade the Midway Islands. They were defeated by the American Navy, and Japan's war ability was permanently impaired after that battle.

Battle of Guadalcanal (August 1942 to February 1943) : American invasion of Guadalcanal Island. The goal - successfully achieved - was to take over the island to prevent Japan from using it as an air base.

Battle of Tarawa (November 1943) : American conquest of the island of Tarawa, which allowed the United States to use the island as a base and destroy Japanese aeronautics during 1944.

There were also significant American victories in the Philippines, Iwo Jiwa and Okinawa. However, Japanese resignation to fight to the death made it clear to American commanders that the invasion of Japan would result in thousands of deaths of American soldiers. From that conclusion, they chose to use a powerful weapon they had developed - nuclear bombs.

Two major cities in Japan - Hiroshima and Nagasaki - were chosen to be bomb targets. The attack took place on August 6, in Hiroshima, and on August 9, 1945, in Nagasaki. The complete destruction of the two cities forced the Japanese government to sign the unconditional surrender in September 1945. Japan's transition after the surrender was all carried out by the United States under the terms imposed on Japan.
