Why aren't you using your usual profile?
Well there were different versions of the IRA back then.In the wider sense you are also wrong.
Just to make you think, the IRA provided the British High Command in Ireland with a bodyguard to protect them from, 'those mad Fenian b#st#rds', between 1914 and 1918.
I don't actually know what the British High Command thought of that.
Same as the UVF was a different organisation.
