After these successes, the IJN now concentrated on the elimination and neutralization of strategic points from where the Allies could launch counteroffensives against Japanese conquests. However, at Coral Sea the Japanese were forced to abandon their attempts to isolate Australia while the defeat in the Midway Campaign saw the Japanese forced on the defensive. The campaign in the Solomon Islands, in which the Japanese lost the war of attrition, was the most decisive; the Japanese failed to commit enough forces in sufficient time. During 1943 the Allies were able to reorganize their forces and American industrial strength began to turn the tide of the war. American forces ultimately managed to gain the upper hand through a vastly greater industrial output and a modernization of its air and naval forces.
