The Pacific theater in the second world war saw some of the worst fighting on land and at sea. It was one of the most complex logistical challenges a military has faced. From naval battles in the Philippine seas to landings at small islands in the central Pacific, the theater stretched almost half the globe. We interviewed Dr. Marc Gallicchio Chairperson and Professor at the Department of History at Villanova University. He was also a Fulbright Visiting lecturer in Japan from 1998-1999 and 2004-2005. Some of his work includes The Unpredictability of the Past: Memories of the Asia-Pacific War in U.S.-East Asian Relations, The Scramble for Asia: U.S. Military Power in the Aftermath of the Pacific War and Implacable Foes: War in the Pacific, 1944-1945 which was the winner of the Bancroft Prize in American History and Diplomacy in 2018.  We look at the Grand Strategy of both sides, its impact on the war, and the legacy it left in Asia.
