I suspect if the cigar was a Clinton metaphor, then it would be the symbol of American values as the the Islamic would see them, i.e. the Clinton/Lewinsky affair.
After eight years, Clinton is the president they knew best - Bush was still new. They obviously neither respected nor feared Clinton (USS Cole, Embassy Bombings, 93 WTC, etc.) and thus had no fear of the new kid on the block either.
I'm inclined to think that the message in the J-Lo letter was the same as that in the known anthrax letters (see #108 above).
Seems to be pretty clear what the cigar meant, as well as the snuff can, and the detergent box cover.
Mr. Atta didn't like girls in the first place! Now just what do you think he thought about Jewish girls.
