The History Ch special glossed over the IRA problems JZD had. I have a good friend that retired as a Colonel after serving 30+ years in "King's Own Scottish Boarderers"... some of the stories had had, as soon as I mentioned DMC went way beyond the simple bombing of the downtown office building. The IRA didn't want any kind of stable employment in Ulster, and ANYTHING it could do to harass, or damage the business was their goal.
