The spike in concern over Syria鈥檚 stockpile of chemical weapons stems in part from worries that an increasingly desperate President Bashar al-Assad might use them against advancing rebel forces in the country鈥檚 21-month-old civil war.

But Mr. Assad also might be sending a different signal to the US and the international community, analysts say. By ordering 鈥渁ctivity鈥� at chemical weapons sites, Assad could be reminding the international powers demanding his departure that his fall would likely be followed by chaos 鈥� in which radical Islamists could get their hands on Syria鈥檚 weapons of mass destruction.

鈥淏y far the greater threat is that the state collapses, with the threat of terrorists getting their hands on these weapons,鈥� says Charles Blair, an expert at the Federation of American Scientists (FAS) in Washington.

US officials claim that the Syrian military has gone as far as loading precursor chemicals for the nerve gas sarin into bombs, NBC News reported Thursday. Their use would have serious consequences for the Assad regime. President Obama repeated this week that any use of the weapons by Syria is a red line for the United States.

The fate of Syria's stockpile of chemical weapons is something that concerns the US. Earlier this year, a Pentagon report concluded that it would take 70,000 troops to find and secure Syria's known stockpiles, Mr. Blair notes.

Publicly, Syrian officials maintain that the Assad regime would never use chemical weapons against the Syrian people. On Thursday, one member of the regime, Deputy Foreign Minister Faisal Maqdad, told Lebanese television that 鈥渢he United States and some European States鈥� were fabricating the chemical-weapons scare to create a 鈥減retext鈥� for intervention in the conflict.

US officials have to consider all the possible motivations behind Assad鈥檚 actions, military experts say. But some are confident the US would act preemptively if it was convinced that Assad was on the verge of launching a chemical attack.

鈥淚f [the US] had knowledge of them loading these weapons onto planes, they鈥檇 go in and take them out right away, I鈥檇 expect to see that,鈥� says Lawrence Korb, a defense analyst at the Center for American Progress in Washington. 鈥淭he problem is that you鈥檇 have to have very good intelligence on where to go to get them.鈥�

But Blair says he can envision a range of ways the US might respond to a chemical attack.

The 鈥渇ast route,鈥� he says, would be to launch a 鈥減unitive鈥� strike in retaliation and to try to take out Assad. The 鈥渓onger route,鈥� he adds, might be to return to the United Nations Security Council to get support for international intervention 鈥� support Russia and China have denied so far.

鈥淭here鈥檚 such a taboo against chemical-weapons use that you鈥檇 have to assume that Russia and China would no longer block UN action,鈥� he says.

Another question is what the international community would do to aid the victims of an attack. Blair says treatment does exist for the effects of some of the chemical agents Syria is thought to possess 鈥� depending on the severity of the impact. But nobody knows for sure that Syria has chemical weapons, or exactly what they have if they do possess them, he says.

The most treatable victims would be those that had quick access to international assistance 鈥� in other words, the victims of an attack near one of Syria鈥檚 borders. But Blair adds that such a step would almost certainly lead to outside intervention, starting with the country 鈥� for example, Turkey 鈥� whose border was affected by the attack.

Still, Blair is far from convinced that Assad would ever use the weapons 鈥� saying that doing so would be 鈥渟uicidal,鈥� something Syrian officials acknowledge.

Assad may be up to something else altogether, Mr. Korb says: 鈥淗e might be using this as a bargaining chip to win himself free passage out of the country.鈥�
