I think the best thing we can do is ignore them completely. To be honest terrorist attacks kill very few people and cause very little damage. Compare them to automobile crashes. Car crashes take hundreds to thousands of times more lives than terrorist attacks. Yet when was the last time the media made a single comment on that?
Well, by following your logic, lets compare death by old age and deaths by terror attacks shall we?
By doing this we can also completely ignore the ones killed in the streets, because there are more deaths by old age than terror killings..are you for real?
The deaths due to automobiles are no accident. The auto industry knows it will make less money with if cars no longer need drivers, because then we'll need less cars per person. So they lobby to keep them off the streets, or at least make sure they always have a driver. This is why we don't have selfdriving cars everywhere; they already exist and work, but profit is more important than lives for those in power.
