The idea of terrorize and kill civilians with weapons of mass-destruction in the hope to break the resistance of a government, comes from Nazi Germany. Hitler authorised full-scale development work on the “pilotless airplane” in June 1942. Nazi Germany used the unmanned aircraft (V1, V2) to bomb London. In total, the V-1 attacks caused 22,892 casualties (almost entirely civilians). More than 10,000 V1’s were launched, 7488 reached England. More than six thousand civilians were killed and eighteen thousand were wounded. The 1150 V2’s that landed in London, killed 2,742 civilians and wounded 6467. The total property damage was 23,000 houses totally destroyed and 100,000 damaged.
