Do you really think anybody here has any idea more than you yourself? At a rough guess, we are not talking here of 2800 fatalities. A few years ago, the IRA was engaged in this sort of activity, and life carried on and the UK economy soldiered on relatively unaffected. If you are asking on a purely financial global economy-wise basis how much effect it will have, I would say just like in those days very little. In humanitarian terms, it is incredibly sad and needlessly tragic, but that was not your concern.
