What military strategy was used in the pacific?

the strategy of "island hopping" was used by the United States in the Pacific theater of world war two. Thought of by Douglas MacArthur, "island hopping" was a strategy that used the technique of jumping from island to island on a chain to control the chain as a whole vs attacking all the islands at once. This helped establish air base's on islands in order to conduct further operations and expand supply lines to more islands.

Actually, both Nimitz and MacArthur based their Island Hopping on Plan Orange created by a joint war college of the War Department and Navy Department for action in the Western Pacific in the 1930s.
