In a statement Monday, Secretary of State John Kerry called the use of chemical weapons in Syria “a moral obscenity” that demands action from the U.S. U.S. government officials have concluded that chemical weapons were used in the attack in the Damascus suburb last week, despite UN weapons inspectors again postponing their trip to the site out of concern for their own safety.

Now the question is what action the U.S. will take against Syria for crossing the “red line” President Obama outlined against the use of chemical weapons. This morning in an interview with BBC, defense secretary Chuck Hagel said the U.S. military is “ready to go” whenever the president decides on the course of action.

What action should the U.S. take against Syria? What are the different options and how would they affect Syrian civilians? Syria’s foreign minister said the country will defend itself with “all means available” in case of a U.S. attack. What’s the plan for ensuring domestic security?
