If you know your history of the British Empire you can find many examples. To cite one, 1932, the distinguished British statesman Lloyd George wrote in his diary: ‘ We have to reserve the right to bomb niggers.’ He was referring to the fact Britain had just succeeded in undermining an international disarmament conference which was attempting to put restrictions on the use of air power to attack civilians. Britain very quickly understood that use of air power to attack civilians was far more cost effective and murderous than using ground forces.
