Tractorat, at work in the UK it was hard not to be working with someone who had not fought in WW1, every family you knew had lost at least one member fighting in WW1, some all their brothers plus the father, my mother lost a brother, no one in the UK wanted another War, and in any case Britain had no resources to fight one. France never intended to be the site of another World War fought on her soil, hence the outcome for France.
Its quite a different generation since WW1 and WW2, I never meet anyone who served in those Wars suffered from mental affects from their experiences, most had been wounded, and a few PoWs, and the PoWs were mainly all treated badly by the Italians, Germans and Japs. It was, 'Just Grin and Bear it', and 'Carry-On'.
