而麦克阿瑟的新几内亚则都是以少胜多的战略战。

MacArthur would have liked to deny this area to the Japanese, but he had neither sufficient air nor naval forces to undertake a counterlanding. The Japanese at Rabaul and other bases on New Britain would have easily overwhelmed any such effort

The campaign on New Guinea is all but forgotten except by those who served there. Battles with names like Tarawa, Saipan, and Iwo Jima overshadow it. Yet Allied operations in New Guinea were essential to the U.S. Navy's drive across the Central Pacific and to the U.S. Army's liberation of the Philippine Islands from Japanese occupation. The remorseless Allied advance along the northern New Guinea coastline toward the Philippines forced the Japanese to divert precious ships, planes, and men who might otherwise have reinforced their crumbling Central Pacific front.
