As far as I'm concerned the situation in Northern Ireland was a total clusterfuck.
It was handled badly by Westminster, a 'military' solution was never going to work, but so much had been committed that no government was going to just pull the army out because a. It would be seen as defeat and b. Heaven alone knows what would have happened.
I lost friends in NI, I was shot at (not a pleasant experience), we all wondered what the fuck we were doing there and were very glad to leave.
My only complaint about the peace process was that it hadn't happened sooner. Politicians have an unfortunate habit of thinking that it is so, and that makes it so. It doesn't.
Anyway, no one was hurt on this occasion, not that that makes it right.
From some of the posts on this thread though, it looks as if sectarian violence is on the rise, so the peace process is perhaps not as sound as thought.
