UN says Syrian rebels used sarin gas. What color line does that cross?

The usual neocon crowd are back crowing for yet another war in the Middle East. They aren’t quite sure whether we should invade Syria, Iraq version-3, or Iran. What the hey? Why not all of the above and throw in North Korea for good measure?

Now the UN says the Syrian rebels have used sarin gas in an attack. So if it’s the rebels using nerve gas and not the Syrian army, does that change the color of the line that’s been crossed? What if, as is likely, both sides are guilty as sin? What if the rebel forces are full of Islamic extremists and members of Al Qaeda in the Arabian Peninsula? Who do we intervene in favor of? Or is this one supposed to be yet another war just like Afghanistan and Iraq—worry about the details later, just get the hell into some war ASAP?
