Having bombed Dublin and, perhaps, a few IRA training bogs in Tipperary, we could not have afforded to be complacent. We would have had to turn our attention to those states which had supported and funded the IRA terrorists through all these years. The main provider of funds was, of course, the USA, and this would have posed us with a bit of a problem. Where to bomb in America? It's a big place and it's by no means certain that a small country like the UK could afford enough bombs to do the whole job. It's going to cost the US billions to bomb Iraq and a lot of that is empty countryside. America, on the other hand, provides a bewildering number of targets.

Should we have bombed Washington, where the policies were formed? Or should we have concentrated on places where Irishmen are known to lurk, like New York, Boston and Philadelphia? We could have bombed any police station and fire station in most major urban centres, secure in the knowledge that we would be taking out significant numbers of IRA sympathisers. On St Patrick's Day, we could have bombed Fifth Avenue and scored a bull's-eye.
