The United States treated the defeat of Japan after Pearl Harbor as primarily its own war and wanted Pacific operations under American direction. Britain accepted American supreme commanders but still expected a major strategic voice, especially as it sought to recover territories lost while fighting in Europe and the Mediterranean. Military priorities, political control, and postwar influence all shaped the disagreement. Growing American reluctance to let Britain use American-built LSTs for independent operations helped drive the Mark III project, supported by Canadian construction. The Mark III grew out of coalition command disputes and Britain's concern for imperial prestige.
