"We could use our precision strike capabilities to target Assad's aircraft and SCUD missile launchers on the ground without our pilots having to fly into the teeth of Syria's air defenses. Similar weapons could be used to selectively destroy artillery pieces and make Assad's forces think twice about remaining at their posts. We could also use Patriot missile batteries outside of Syria to help protect safe zones inside of Syria from Assad's aerial bombing and missile attacks."
