By April L. Brown LOOKING BACK No Promised Land: The Shared Legacy of the Castle Bravo Nuclear Test This year marks the 60th anniversary of the Castle Bravo to the children of Israel who had been saved by their enemies and led to the nuclear detonation in the Marshall Islands.

These islands rarely held the food or water supplies necessary to sustain their temporary populations. In 1947, a year after the two Crossroads detonations, the United Nations awarded trusteeship of the Marshall Islands to the United States. Part of the U.S. charge was to “protect the inhabitants against the U.S Department of Energy loss of their lands and resources” and to “protect the health of the inhabitants.”6 Once operations in the Pacific Proving Grounds switched from military to U.S. civilian control in 1947 under the newly formed Atomic Energy Commission (AEC), a new cloud of secrecy shrouded future The 15-megaton Castle Bravo nuclear test in the Marshall Islands on March 1, tests.
