Kahoolawe was not sacrificed for anything.  It was never a place of habitation.  Attempts to farm and raise livestock were total failures.  The soil is not good and there is no fresh water except when it rains.  It was put to its best possible use when the US military used it for live-fire training for ground troops, ships and airplanes.  Oh, but it was declared sacred by some Native Hawaiian activists, everyone ran scared, and it no longer can be used by the military.  The power of the word “sacred” is truly amazing.
