Why did the US want to gain control over the island during the world warr 2?

During World War II, the U.S. sought to gain control over strategic islands, including those in the Pacific, to establish military bases and supply lines. Control of these islands was crucial for launching operations against Japan and securing key naval routes. Additionally, capturing these territories helped to diminish Japanese influence and bolster Allied efforts in the region. Ultimately, this strategy was part of a broader campaign to ensure victory in the Pacific Theater.
