I know this is done to death but he successive Government Ministers around the period 1974 to about the late 1980s had:
Callaghan (RN), Heath (I think Army Intelligence), Enoch Powell (Army Intelligence?) Pym (Army I think), Benn (fighter pilot), Healey (Army), Whitelaw (Army), Carrington (Tanks) and so on and so on - all or most had served. Most with WW2 combat experience. But perhaps crucially all were non professional - simply had to serve because of the circumstances and their time.
It must have given them a feeling,an understanding and a massive advantage understanding for the problems faced by service people of all ranks at all levels.
There is simply a complete absence of that sort of experience on the present opposing benches, and so it shows, deeply and almost every week.
Many of the 1940-45 Churchill war cabinet had WW1 combat experience and service.
Different times, people, country.
Hardly helpful to this thread, do carry on.
