Most of the world (including the U.S.) seems to be relieved now that there is affirmative progress towards eliminating Syria’s ghastly chemical weapon (CW) stockpiles, thereby avoiding (at least for now) a military strike that no one really wanted to undertake. The Syrian government has announced that it will soon join the Organization for the Prohibition of Chemical Weapons (OPCW). Joining the OPCW will immediately trigger an obligation on Syria’s part to issue a written declaration identifying the number and types of CWs it currently possesses. With history as a guide, we can safely predict that it will be an incomplete and inaccurate declaration. That is true even if Syria fully intends to come clean regarding its CW stockpile. This is the point where good intentions can go awry. The problem here is that no one really trusts Syria. The consequences of such mistrust are informed by experiences in Iraq and Libya over the last 20 years.
