The United States and Russia seem to be on a collision course in Syria, which is just fine for the regime in Damascus.
On Sunday, a U.S. Navy F/A-18E Super Hornet shot down a Syrian Su-22 fighter bomber that was conducting operations near positions held by the U.S.-backed Syrian Democratic Forces outside the besieged Islamic State stronghold of Raqqa. The shoot-down took place after repeated warnings for the Syrian aircraft to disengage, and the Coalition justified the action as being "in accordance with rules of engagement and in collective self-defense of Coalition partnered forces." The next day, a U.S. Air Force F-15E downed an Iranian-made Shahed 129 armed drone near the site of a U.S.-backed training base at al Tanf for rebels opposed to Syrian President Bashar Assad.
