I understand, but that means that the communication from those “arranging” the stuff need to ensure that these types of tradeoffs and decisions WILL be made and then when those that still complain do so - that prior announcement should be well exercised and not underplayed.
People who’ve been told the rules - when they have - should not be allowed to then moan and groan about them.
Good heavens if those who fought in these battles had acted in this way we’d all be speaking German (not to sleight those germans who bravely fought for their own country).... but instead to sleight those who should look to their predecessors sacrifices. After all the memorials and commemorations are to acknowledge and consider what THEY did.
For Britain, the equivalent day is generally held to be 'The First Day on the Somme' which took place nearly three weeks earlier - the site of that battle is where the Thiepval memorial is located.
