There are many points of view, all are valid. I seen Britain suffer greatly from terrorism on its shores.
I believe 'they' would far rather have given over the 32 counties back in the twenties. What have they gained?
I don't think the Northern Ireland problem has been about Britain refusing to let it go. It's a British created problem of course, but the last 40 years it has been about the people of Northern Ireland, some want one thing, others want another.
