A more reasoned responce.
I try and see both sides of an argument, yes horrendous crimes have been commited against the Irish, but in an era and at a time when such things were considered normal and acceptable practice (like the taking of native American lands by the white settlers, very analagous), but it's impossible to re-write history, at any given point you have to start with what you have at that here and now.
Seperating Ireland in the first place was wrong, but it happened, so 40 odd years later there was no point trying to say it shouldn't have happened, besides had it been reunited then it would now be totally bankrupt as the republic owes a LOT of money (much to the British government who baled them out).
The British army did first move back (in force) into NI to protect the catholics, that is fact, Bloody Sunday was a stupid F'up and dreadful, it was the wrong people (the para's) with the wrong mindset and tranining (for war) in the wrong place doing the wrong job, but it happened, the many years of violence from BOTH SIDES was wrong, the moderates on both sides of the divide during this time outnumbered the pro violence (look at voting history), I strongly dislike the Protestant marches as they are a real 'ram it down the throat' provocation and childish in the extreme, however the fact is that once the violence ended (on both sides) the lot of everyone has improved immensely, NI is now run as a pseudo autonomous state which while making neither side 100% happy, at least makes both sides happier.
Also remember that during the troubles the majority of organised crime in the area was controlled by the paramilitary's on both sides, prostitution, drugs, smuggling (tobacco and alcohol), protection, hardly (either side) great freedom fighters for their people!
That the IRA were in league with that bastion of world peace Gadhafi who the US also loved to hate seems strange.
I would remind you who's government brokered the Good Friday agreement that started the 'outbreak of peace'.
