1946, the United States detonated an atomic bomb at Bikini Atoll in Micronesia in the first underwater test of the device. The impetus for the test, which was known as "the Baker explosion" (left), was President Harry S. Truman's December 1945 directive stating that joint testing of nuclear weapons would be necessary "to determine the effect of atomic bombs on American warships." Bikini was chosen because of its isolated location.

The U.N. strategic agreement that gave trusteeship of the area to the United States also allowed further bombing in the area, and so precipitated the Bikinians’ dire health situation. Today, the people of Bikini remain scattered throughout the Marshall Islands and the world as they wait for the radiological cleanup of Bikini to begin in earnest.
