The U.S. goal remains de-escalating the conflict, but Spicer made clear that "we will always preserve the right of self-defense" should actions be taken against the U.S. or coalition forces.
While the USA -led coalition says it is focused on fighting the Islamic State, it will nevertheless respond when they feel threatened by the Syrian regime.

This effort to work with partners, however, doesn't mean that the US won't down Syrian aircraft if necessary. The official says the drone was a Shaheed 129 and appeared to have been operated by "pro-regime" forces.
