カートホイール作戦
Allied success in the Solomon Islands campaign prevented the Japanese from cutting Australia and New Zealand off from the United States. Operation Cartwheel — the Allied grand strategy for the Solomons and New Guinea campaigns — launched on June 30, 1943, isolated and neutralized Rabaul and destroyed much of Japan's sea and air supremacy. This opened the way for Allied forces to recapture the Philippines and cut off Japan from its crucial resource areas in the Netherlands East Indies.
