Why did Iwo Jima happen?

Answer 1

Just how far do you want to be taken back? Perhaps Guadalcanal, when we realized island-hopping was our only hope for beating the Japanese, or even further? Maybe Midway, when the United States managed to deal its first major blow against Japanese dominance in the Pacific, leading to the Guadalcanal/Solomon Islands campaign, or maybe to the start of it all? Pearl Harbor, where we realized that the threat of Japan was VERY, VERY real and that Japan had to be stopped in any way possible? Take your pick.

Answer 2

Iwo Jima was an island off the coast of Japan that was in bombing range from the Japanese mainland so the United States wanted to get the island so they could attack the mainland but it also would be a perfect place for crippled B-29's to land after they attack Japan, as opposed to them splashing down into the Pacific.

Answer 3

1- It was one of the islands that the Allies needed to capture to advance closer to mainland Japan. 2- The airfields on the island were used to launch bombing raids on Japan.
