public transportation rather than airliners? i think it s very possible, obviously inspire magazine is unfortunately an inspiration for jihadists for years. i think the real question right now, if this was al qaeda, does this signal a resurgence of this terrorist group? a lot of people have been focused on isis for the last several years and ignored the threat from al qaeda. if we are seeing this shift, it is obviously very troubling. leland: when we are talking about these different groups, when you are talking about all these disparate groups, at some point, does it really matter which group or is it sort of an amorphous blob of radical islam?
