CSIS, 3 Jun 08: Israeli and Syrian Weapons of Mass Destruction
Both Israel and Syria have long been involved in creating weapons of mass destruction and the means to deliver them. The attached two reports look beyond the narrow issue of nuclear weapons, and summarize developments in each country’s full range of weapons of mass destruction -including chemical and biological weapons - and delivery systems. Both reports are deliberately conservative, avoiding scare or worst case sources and estimates.
The link above contains both reports in a single pdf file. They can also be downloaded separately:
