Greg Scoblete asks: "Should the U.S. intervene militarily if the Assad regime uses chemical weapons against the rebels?" Why it might not be a good idea:

According to the Pentagon (and outside experts) efforts to neutralize Assad's chemical stockpile could entail upwards of 75,000 troops and days of airstrikes. And, as the Times piece notes, bombing chemical weapons depots could simply release the toxins into the air — the very result everyone is trying to avoid. Many of those stockpiles are in urban areas and efforts to destroy them may also facilitate their uncontrolled spread if they're not entirely destroyed at the outset.
