What if Op Motorman had been run differently, without the effort to minimise casualties and with a clear intention to force the IRA to stand and fight? If the border had been sealed, and the troop deployment had been made relatively openly, what would have happened? Would there have been re-enactments of the Warsaw Rising in parts of Londonderry and Belfast, with IRA prisoners marching off to POW camps while crowds of refugees gathered at border crossing points? Would the Republic have intervened militarily (say, by forcing a way across the border to let refugees out, or let arms in)? Would the total number of people killed have been more or less than the total for the next 20 years? Would the resultant population shifts have pacified Ulster for a generation, or just created another generation of martyrs, or both? I know that this is not how we do things in this country, and the UN and other countries would have kicked up a storm about our abuse of UK citizens, but just imagine if a British PM had looked into the future and said, "We can't fix this problem like this inside of a generation, and I'm not prepared to allow people to be blown to bits for the next 25 years. Let's stop this, right now."
