Dean,[16] reported that the majority of North Korean cities and villages he saw were either rubble or snow-covered wasteland.[17][18] Dean Rusk, the U.S. State Department official who headed East Asian affairs, concluded that America had bombed “everything that moved in North Korea, every brick standing on top of another."[19]
