think you are mostly joshing, not 100% sure if, and where, or where not .. the Northern Ireland trouble was basically nationalistic .. course you know too the IRA split after the Anglo-Irish Treaty .. http://en.wikipedia.org/wiki/Irish_Republican_Army
mostly they issued warnings re their bombings, too .. later anyway i think .. they were a more civilized terror group ..
one thing is certain negotiation of grievances is an historically part of every ceasefire against any terrorist group ..
