[Phil] I've had thoughts along those lines - the proportion of the Northern Irish population killed in Omagh was greater than the proportion of the US population killed at 9/11 so would Britain have been justified in launching missiles at Boston? (Of course in parallel with that thought I would vote for the unification of Ireland under the right conditions.)
(Phil) Probably quite a lot though to be fair the average donor may not have known what proportion, if any, went to the IRA. But the organisers certainly must have done. Nobody likes to talk about this, do they?
(SM) Given the respective number of deaths I'd say rather the opposite and it's all a bit dear-old-lady-has-seen-a-spider. At least we haven't seen an arbitrary country bombed yet.
