Actually, my rough figures very much overstated the IRA's imact on civilians.

Here are the actual figures from the CAIN website:

A total of 1706 deaths are attributed to the IRA. Of that 1011 (or 60%) were British Security; 516 (or 30%) were civilians; 7 were Irish security; 32 were Loyalist paramilitary; and 140 were Republican paramilitary (their own and others).

Let's compare the IRA's record with other groupings:

British Security (i.e. RUC, British Army, UDR, etc.) are credited with 363 death of which 192 (or 53%) were civilians.

And Loyalist paramilitaries are credited with 991 death of which 864 (a whopping 87% were civilians).

Not only was the IRA much more discriminating than the Loyalist paramilitaries, there were much mroe discriminating that British security services.

Quite frankly, IMO a force for which overall 70% of it's 'victims' were other combatants cannot be termed a terrorist force.
