Yes, but they did try. They just did it in a way that made everybody unhappy. Expecting pre-WW2 Britain to act magnanimously is not exactly realistic though.
But they didn't try with the civil rights issues, at all. And that was the only option open to anybody at the time.
To be honest Grinner, on this island expecting Britain at any point to act magnanimously was never realistic. If you look at the history books Ireland gave Britain every chance. The history books are struggle after struggle, with alternate means, parliamentary and violence. The violence was the only thing that ever brought Britain to negotiate, so the IRA are Britain's Pavlov's dogs. By ignoring all of our movements Britiain showed Ireland that violence was the only way to get her attention.
So yes it's a difficult siutuation, but being proud of Britain's miltary history, which Britain is, on one hand and shrugging your shoulders at the countries it destroyed along the way on the other is not really realistic.
So while you can draw lines as in pre and post WW2, from an Irish perspective it's been one long occuptaion, enforced with a gun.
And if you ask most of the lads here to name the 5 worst acts by Britain in Ireland, I'd wager they'd be almost all post WW2, so not all that much changed for Ireland.
disclaimer - None of this btw takes any of the horror away from events like the death of the two signallers. Undefendable and still shocking 25 years on. It's just context.
