Some excellent and useful stuff from the Middle East Quarterly:

On Syrian WMD, a two-parter:
Dany Shoham, “Guile, Gas and Germs: Syria’s Ultimate Weapons,”
MEQ, Summer 2002
Dany Shoham, “Poisoned Missiles: Syria’s Doomsday Deterrent,”
MEQ, Fall 2002.
And then this:
Eyal Zisser, “Does Bashar al-Assad Rule Syria?” MEQ, Winter 2003.
