The UN inspection units have been in Syria for days, since before the recent alleged nerve agent attack.
Why would Assad allow the largest attack using nerve gas in twenty-five years knowing the inspectors were right there?
Would Islamists murder their own people to convince the world powers to step in on their side?
Islamists in Egypt recently forced the government to use force to break up Muslim Brotherhood terror activities.
Extremist Muslims routinely commit murders, rapes and other forms of criminal acts.
In Syria, both sides are allied to terrorists.
Neither side is acting honorably, therefore the US can't fully commit to either side.
Before the President states that the "redline has been crossed", we need to be certain about which faction may have used CW's.
