Sheikhs are peace loving. I doubt very much they have the funds and the motive to purchase weapons on that scale. This isn't just some community ethnic civil unrest. Syria in the last couple years have attracted infamous terrorist outfits battling each other out. If this is a proxy war there aren't that many factions. Something else must be attracting them. I don't think govts are the main sponsors of this war.
I keep hearing chemical weapons and such... that's biological weapons. Govts can't be acting alone in this respects. When I was studying politics, biowarfare was just beginning and there were little information about it. If there's an odd strategic diversion like Syria, then I suspect this adheres to a novel strategic framework new to conventional warfare. It's like a new 9/11 wave.

In early 1998, the inspectors surprised the Iraqi's by pursuing the human experiment issue. Few now recall that it was this issue that provoked the first Iraqi shutdown of the United Nations Special Commission (UNSCOM) operations. Scott Ritter, who lead the UNSCOM team, reported in an article which appeared in The New Republic:
"In January of this year, we embarked on an effort to expose Iraq's use of biological and chemical agents on live human test subjects....we had received evidence that 95 political prisoners had been transferred from the Abu Gharib Prison to a site in western Iraq where they had been subjected to lethal testing under the supervision of a special unit from the Military Industrial Commission, under Saddam's personal authority. But just as we began moving in on facilities housing documents that would support our contention (for instance transfer records of prisoners) Iraq woke up to the danger and ceased all cooperation with us."

"Prior to the UN team's aborted efforts to obtain the prison records, the facts that they learned about Iraqi field tests were grisly. Prisoners were tied to stakes, bombarded with deadly bacteria and gases from bombs a few feet away or dropped from an aircraft and died in agony. At other times they were locked in chambers while anthrax was sprayed from jets mounted in the ceiling. Death came from internal hemorrhaging. In one experiment Iranian war prisoners were the 'test subjects' in another Iraqi criminals and Kurds were used. The Kurdish leader Massoud Barzani claims to have evidence that 2000 Kurdish men who were abducted in 1982, were used to test Iraq's first generation of chemical weapons." See Johnathan D. Moreno, Undue Risk: Secret State Experiments on Humans.
More recent allegations have been made with regard to North Korea's use of political prisoners in both chemical and biological experiments. The most notorious Hoeryong Concentration camp (officially Kwan-li-so penal labour colony No. 22, for political prisoners, know as Camp 22. See: http://en.wikipedia.org/wiki/Hoeryong_concentration_camp
North Korea is not alone, although it perhaps runs a far more efficient protocol for using specific sections of its prison population for biological and chemical experiments. Disturbing as these reports are, alleged use of political prisoners in biological experiments in Syria and Iran is of grave concern as well. While the accusations are unconfirmed and can not be substantiated in the public domain, it is likely such experimentation has taking place. Assad's use of sarin against his own people, does not bode well for supporting human rights and opposing chemical and biological weapon use. Both Syria and Iran in tern significant numbers of political prisoners and it is this population which is the most vulnerable to abuse and possible use in biological and chemical experiments. Adra Prison in Damascus, handles an estimated 10,000 prisoners with significant political prisoners and human rights activists. Tadmor Prison in Palmyra (which closed in 2001), was infamous for 'extremely brutal abuses.' General Mustafa Tlas (who by the way has written on germ warfare as an effective weapon of war) stated that he ordered the execution of 150 prisoners a week, for many years, previously held in Tadmor.

If Syrians were exposed to some unknown contaminants, that could spread elsewhere when they flee. I'm not saying we shouldn't embrace Syrian refugees, I just think ordinary folks or ordinary scientists I should say, should explore the possibility of potential biological agents Syria could be harboring and put together somesort of biowarfare matrix on how and where contaminants could spread and measures to counteract.
