Misty, I have just recently started reading Chomsky and it is pretty good stuff, I believe it will age well. I think that the long tail on "Failed States" will be impressive. I am not sure he ever wanted impact, as he never really offers solutions, he just bonks impractical ideas on the head and gently herds you towards his way of thinking. Pretty tough to get attention if you are not willing to tell people what to do.
Anyway that is about as bright as I get at quarter to five in the morning. Good luck.
