Is Syria Worth a War with Russia?

The Russians have stated they’ll fire back if they take any fire from American forces in Syria. With both sides closing in on the last ISIS strongholds, they are bound to meet on the battlefield. What would America’s response be to taking fire from Russian forces on a battlefield where the U.S. has no legal right to be? Is Syria worth a war with Russia? Daniel Larison says no at The American Conservative:

The U.S. should never have expanded the war on ISIS into Syria, and American forces have no business operating in Syria. U.S. operations in Syria have no legal basis, and the U.S. would be wise to pull out everyone it has in Syria and to end any support it is still providing to armed groups there….

If the U.S. insists on protecting its proxies in Syria, that creates the danger that the U.S. could easily end up bombing the forces of another state and potentially triggering an avoidable conflict….The U.S. war in Syria is illegal, but more than that it serves no discernible American interest.
