While the United States is a world leader, we have little interest in a Syrian civil war. Our main concern should be to help the victor pick up the pieces and reintegrate their nation into the community of nations. Even then our actions should be tempered by the desires of Syria's immediate neighbors.
It is understood that Syria's neighbors have concerns about the use of chemical weapons in their civil war. We petition the White House to use the Secretary of State to encourage Israel, Jordan, Turkey and Saudi Arabia to decide if they should band together to take any action in Syria.
The Middle East should handle the Middle East and we should support our allies in that region diplomatically for any actions they take or militarily for any consequences they suffer.
