This kind of thing is happening all the time. Out of the milions of instances which must be available, I will choose one which happens to be verifiable. During part of 1941 and 1942, when the Luftwaffe was busy in Russia, the German radio regaled its home audiences with stories of devestating air raids on London. Now, we are aware that those raids did not happen. So with innumerable other events of the past ten or twenty years.
History is written by the winners.
In the last analysis our only claim to victory is that if we win the war we shall tell fewer lies about it than our adversaries. In spite of all the lying and self-righteousness that war encourages, I do not honestly think it can be said that that habit of mind is growing in Britain. Taking one thing with another, I should say that the press is slightly freer than it was before the war. I know out of my own experience that you can print things now which you couldn't print ten years ago. War resisters have probably been less maltreated in this war than in the last one, and the expression of unpopular opinion in public is certainly safer.
