Battle of Okinawa - Aftermath

Aftermath

Ninety percent of the buildings on the island were destroyed, and the tropical landscape was turned into "a vast field of mud, lead, decay and maggots".

The military value of Okinawa "exceeded all hope." Okinawa provided a fleet anchorage, troop staging areas, and airfields in close proximity to Japan. The U.S. cleared the surrounding waters of mines in Operation Zebra, occupied Okinawa, and set up the United States Civil Administration of the Ryukyu Islands, a form of military government, after the battle. Significant U.S. forces remain garrisoned there, and Kadena remains the largest U.S. air base in Asia.

Some military historians believe that the Okinawa campaign led directly to the atomic bombings of Hiroshima and Nagasaki, as a means of avoiding the planned ground invasion of the Japanese mainland. Victor Davis Hanson explains his view in Ripples of Battle:

...because the Japanese on Okinawa... were so fierce in their defense (even when cut off, and without supplies), and because casualties were so appalling, many American strategists looked for an alternative means to subdue mainland Japan, other than a direct invasion. This means presented itself, with the advent of atomic bombs, which worked admirably in convincing the Japanese to sue for peace, without American casualties. Ironically, the American conventional fire-bombing of major Japanese cities (which had been going on for months before Okinawa) was far more effective at killing civilians than the atomic bombs and, had the Americans simply continued, or expanded this, the Japanese would likely have surrendered anyway.

In 1995, the Okinawa government erected a memorial named Cornerstone of Peace in Mabuni, the site of the last fighting in southeastern Okinawa. The memorial lists all the known names of those who died in the battle, civilian and military, Japanese and foreign. As of June 2008, it contains 240,734 names.
