In Woodward's NSC scene, they consider Iraq and Russia. I've also been told that Iran, Iraq, and Saudi Arabia are the three candidates for state sponsor of al Qaeda which are seriously considered in Washington. Pakistan (or Pakistanis, as in ISI) would be another natural candidate.
I've always been surprised that China is almost never speculated about as a possible source for the anthrax letters. Although I've never read about it and have no documented proof, common sense suggests that China almost certainly has an anthrax program. So they'd be in a position to take fast advantage of 9/11, and they'd have the motivation to do so. In fact, they'd have a number of motivations:
- The opportunity to test a biowarfare agent in a real-life situation, under cover of a false flag.
- The desire to wreak some havoc in the U.S.
- Goading us with the aim of encouraging all-out war between their two main enemies, the U.S. and the Muslim world (they would hope to stand back watching while the two of us weakened ourselves, leaving China in that much of a better position).
- Possibly revenge for the "accidental"(?) bombing of the Chinese embassy in Belgrade.
I hasten to add that I do not believe that this theory is likely to be true, but, in the absence of concrete evidence, it's hard to say that this theory is really any more bizarre than some of the other theories that have been proposed.
There's also the possibility of a domestic U.S. source, of course. This would most likely be some small internal group acting without official sanction or knowledge. (In fact, a similar sort of rogue group could have operated in any of the foreign countries mentioned above also, acting under the protective cover of a secret defense or intelligence establishment.)

Iran-contra is the most wellknown modell, once again.
