I cannot remember those joyous events as I was not yet born, but I know plenty of people who can. I also know plenty of people who spent six years of their lives, at quite young ages, suffering the horrors and deprivations of the war.
I don’t think WW2 is yet ready to be consigned to the airbrush department. It did happen, it was horrendous, Britain had no option but to become involved, many people alive now have parents and grandparents who lived through it (or often died during it) and the anniversary of its ending must be marked. Furthermore, all those under 70 who have been fortunate enough not to have to endure such atrocities would do well to remember just how lucky they are and these celebrations may help them do so.
