Summer Assignment

This is an article about the Gas attacks on the Syrian people by the Syrian Government. This brings an interesting knowledge question to the table. How did the United States Intelligence services know that the Syrian government is responsible for the attacks? Could it have been a rouge Syrian General or Army Commander? Unsanctioned by the Syrian Government. And who is to say that this was from the Syrian Government at all?! Could it be from the Rebel Forces? Or from another entity entirely. Another Knowledge issue could be the use of Chemical Weapons. What is it about Chemical Weapons that causes the World to pay attention to the conflict? Over 90,000 people have died since the conflict has started and the world all of the sudden pays attention after 1,400 people die from the use of chemical weapons? This seems very sad.
