If your dub had been brought up in the UK he would have lived with threat of terrorism from the IRA for decades. I have seen a prominent building in my hometown destroyed with the loss of many lives. Perhaps if he had heard of Enniskillen and Omagh and Newry, maybe he would be a little more pragmatic about the current threats .
Of course the numbers of potential casualties are higher, that is progress, but I maintain that it is just as evil to blow up 28 people as it is to blow up 2800. The historical examples quoted above show that indeed "There is nothing new under the sun" . One of the things about the WT writing is the rosy picture they paint of the past. A real look at history shows it to have been largely a mean and cruel time . Anybody mention the slave trade??
