Please don't join the jingoists who spout militarist nonsense. Not when we were talking seriously.I’m sure you’d be narked if your boss didn’t pay you your last months money after you quit citing “well you were the one who started playing ‘silly sods’ for wanting out and resigning”. I suppose you could key his car in retaliation.
But you would right expect people to behave in a professional and fair way, not like a bunch of spoilt brats who haven’t got their way. This is what I hope the EU are doing here and it’s just an overzealous bureaucratic process at play and not some underhand tactic because they feel we had them over on vaccines or the such or they just want to punish us for leaving. Because then, then they will have seriously underestimated British resolve and that hasn’t ended well for Europeans in the past.
If you just meant our resolve to commit self-harm we've certainly shown how good we are at that. "The English vice" is now policy.
