Our government has chosen the course of Russian Roulette -- You are correct -- it's gonna take another city to go up in flames before "Homeland Security" starts to seriously clean house right here in the USA.Until then, unfortunately, the question will remain: Which city will be sacrificed?
Why do you assume the singular?
My fear is that when they strike, it will be a coordinated strike at several major cities. Remember, the only reason the 9/11 attack was limited to two targets was because the FAA was quick on its feet and grounded the planes before they could be taken over.
IIRC, there were a dozen of the grounded planes that had terrorists on board. I don't know what their targets were, but I presume they were spread out around the country.
If my fears are borne out, there won't be a "lesson" involved -- even a "costly" lesson -- unless "this is why we're wiped out" can be construed as a "lesson".
