Nobody supports what happened last Saturday in London. But what about stopping it happening? As long as we are in Ireland, people will be letting off bombs in London. I can see that we are a colonial power holding down a colony. For the rest of the time violence will recur again and again as long as we are in Ireland. People in Northern Ireland see themselves as subject peoples. If they were just criminals or psychopaths they could be crushed. But they have a motive force which they think is good.
