the problem is not many people push it in the mainstream, just like vegas was forgotten.
the age of social(ist) media and always wanting to move on to the next best thing.
people have been conditioned to be trendy and "that's old news, who cares" type mindsets so they no longer care about finding the real answers.
most of those and the jihadi terror cells were really cia-backed cells to be the "boogeymen" in order to justify wars and the military industrial complex.
it's the age old dilemma, without light there can be no dark, without evil there can be no good, without bad guys then there'd be no justification for having standing armies and on and on it goes.
