Frankly there is no conclusive proof that Syria has used chemical weapons. It is more like used by the rebels to put the blame on Assad and invite US action.
The US wanting a ruse to attack Syria has latched on to this. Remember the talk of WMD in Iraq was a big lie. Why not the same thing in Syria ?
The only saving grace is Obama, who has held off the attack, but that is because he is an Afro American. A white president would have launched an attack weeks back.
It will be a disaster for America to fight another war with a trillion dollar deficit. Anybody thinking about it ?
