Terrorists have, by the looks of it, been very innovative in their methods to scare the pants off people, should the claims by various governments all across the globe who carp on about anthrax attacks and website hacking as a manifestation of terrorism have an iota of truth attached to it.
In light of such R&D invested by the alleged terrorists in avenues apart from the now inaccessible flight schools, admission into which is tougher than getting a H1-B visa to the US, it is but natural for the evil-mongers to look for methods by means of which they can inflict the maximum mayhem without people knowing what hit them.
With sound financial backing, the attempts to bring about a global recession could also be a terrorist scheme. Indeed so.
