Reports from Syria today indicate that the government is preparing to use chemical weapons against the rebels. What no one is talking about is the fact that Syria has no capacity to produce such weapons. Israel would never permit them to have such production facilities. Remember what they did to Syria's only reactor?
So, where did they come from? In the weeks immediately before and after the 2003 U.S. lead invasion of Iraq, there were persistent reports that Saddam's government was transferring it's chemical weapons to, you guessed it, SYRIA.
Why would he do this? Simple: They would be useless against troops prepared for them - as the U.S. forces and their allies were. If they could not be found, perhaps the U.S. could be forced out so he could retain power. Of course, the reality is that over 500 small caches of chemical weapons were in fact found - but since the Bush administration thought they had a lot more, the press spun the story as "there were NO WEAPONS".
Personally, given that after 9/11 Saddam aligned his government with the Taliban and Bin Ladin (Taliban and allied forces were treated in Iraqi hospitals so they could return to the fight long before the U.S. invasion), and the fact that the small amount of nerve agents found still was enough for many terrorist attacks, I believe that the invasion may very well have stopped several WMD attacks on the U.S. and other Western governments. However, if Saddam's nerve agents turn up in Syria, the media will have to eat a lot of crow.
If the Syrian government forces start using nerve agents, they almost certainly were made in Iraq. Remember that, if and when it happens - because the mainstream media won't mention it.
