(That is *assuming* that it bears up under scrutiny better than UFOs etc. ...)
We need to know that we are neither more virtuous nor wise than.. most other homo-saps: same old Gaussian. This is *not* the picture portrayed in our classrooms (just as the pictures of Us portrayed in other classrooms possesses its own xenophobic content - we see).
If.. after all, WTC.. the event, proves incapable of shocking *any* reevaluation of a bevy of our assumptions, our policies and - certain actions since WW-II (??) then I believe we shall succumb to terminal fantasies about how the rest of the planet lives. Hasten our demise and likely that of many others.
So I think - by all means do we need to discover that of which we are capable and might.. have done to ourselves (always - "for our own good!" via the perps' rationale). Especially: "at this time".
