U.S. military chief: World risks becoming immune to crises

The top U.S. military official warned Tuesday that the world risks becoming immune to the suffering caused by escalating global security threats.

Army Gen. Martin Dempsey, chairman of the U.S. Joint Chiefs of Staff, said it would be "a historical shame" if the world doesn't realize it is reaching a point where it becomes insensitive to the magnitude of the problems caused by international crises.
