Washington: The US and its allies are closely monitoring Syria`s stockpiles of chemical arms and portable anti-aircraft missiles, a State Department official says, amid concerns that the country`s unconventional weapons could fall into the hands of terrorist or militant groups while the 11-month-old uprising continues.
"Syria is a country of significant proliferation concern, so we monitor its chemical weapons activities very closely," the State Department official said, speaking on condition of anonymity to discuss intelligence-related matters.
"We believe Syria`s chemical weapons stockpile remains under Syrian government control, and we will continue to work closely with like-minded countries to impede proliferation (of) Syria`s chemical weapons program."
The official added that the US is in discussion with its allies on ways to ensure that Syria`s stockpile of portable anti-aircraft missiles, called Man-Portable Air Defence Systems, or MANPADS, aren`t stolen or diverted. "We are consulting with allies and partners as we plan for a variety of contingencies," the official said.
Republicans in Congress, meanwhile, have been critical of US efforts to secure Libya`s chemical and unconventional arsenals, saying the Obama administration should have responded more quickly during that crisis and now faces the task of trying to account for thousands of missing portable anti-aircraft missiles.
"We got off to a slow start with Libya," Rep Edward Royce, R-California, chairman of the House Foreign Affairs subcommittee on terrorism, non-proliferation and trade, said in a recent interview.
Libya halted its weapons of mass destruction programs in 2003 as part of an agreement reached to improve relations with the West. Muammar Gaddafi`s remaining stocks of mustard gas were awaiting destruction when rebels drove him from power last year.
Gaddafi, however, maintained a large conventional arsenal, including an estimated 20,000 portable anti-aircraft missiles, believed to be the largest stockpile outside of a MANPADS-producing country.
Syria is believed to have nerve agents as well as mustard gas, Scud missiles capable of delivering these lethal chemicals and a variety of advanced conventional arms coveted by insurgent and terrorist groups, including some late-model MANPADS and anti-tank rockets. US intelligence officials in the past have said Syria has conducted biological weapons-related research but have stopped short of saying the country had taken the next step and built bioweapons.
The task of securing Syrian President Bashar Assad`s arsenals is complicated by the fact that the US can`t be certain it knows how many weapons Syria has and where they are stored. "There`s a lot to worry about and oftentimes very little information to assess the situation," said Matthew Schroeder, a small arms researcher with the Federation of American Scientists.
According to independent military experts, Syria had more than 4,000 portable anti-aircraft missiles in the late 2000s. But Syria is a major customer of arms suppliers, including Russia, and could have purchased many more since then.
Israel and its allies long have suspected Syria of seeking at least the capacity to build atomic weapons, and the UN nuclear watchdog agency has pressed for information about its nuclear research program. But a 2007 Israeli airstrike on a suspected plutonium-producing reactor under construction in northern Syria may have derailed Syria`s nuclear ambitions.
Israeli officials this month said their main worry is that Syria`s ally, the militant group Hezbollah, could acquire Syria`s Soviet-design S-125 surface-to-air missile systems, which could hinder operations by the Israeli air force. But Israeli officials also said they were concerned Hezbollah could get its hands on chemical weapons and missiles capable of striking deep inside Israel.
Syria`s chemical arms are believed to be secure for now because they are stored at weapons depots in rural areas, officials and experts say, away from the urban centres where most fighting is now taking place.
"So far at least I don`t think we`ve seen any examples among troops that are guarding these sites or any activities to suggest the chain of command is weakening," said Leonard Spector, a former senior nonproliferation official with the National Nuclear Security Administration. "I think what people are worried about is that the situation could become increasingly chaotic and the chain of command breaks down."
But if Syria`s control of its arsenal collapses, he said, the consequences could be worse than in Libya. "It`s a hundred times more serious in Syria," he said.
Andrew Shapiro, the assistant secretary of state for political-military affairs, said this month that the US has helped recover 5,000 of Libya`s portable anti-aircraft missiles, or about a quarter of the number the Gaddafi government is thought to have amassed.
Shapiro said many of the weapons that have not been accounted for were likely used in training, had broken down or were fired by rebels while fighting the regime. A substantial number probably remain in the hands of militias who defeated Libyan government forces and were often the first to "liberate" weapons sites, he said.
"Yet clearly we cannot rule out that some weapons may have leaked out of Libya," Shapiro said in a talk to the Stimson Centre, a Washington nonproliferation group.
The US plans to spend USD 40 million helping Libya secure and recover its stockpiles of portable anti-aircraft weapons, Shapiro said. The US also will conduct an inventory of all Libyan weapons storage areas and has two mobile teams assigned to respond to the discovery of new portable missile caches, he added.
Royce and other Republican lawmakers said that if Syria`s arsenals are threatened, the Obama administration should move faster than it did in Libya to secure unconventional weapons.
