So the Russian threat is simple: you attack us and we will attack US forces in Syria. Of course, Russia will vehemently deny targeting US servicemen and insist that the strike was only against terrorists, but both sides understand what is happening here. Interestingly, just last week the Iranian Fars news agency reported that such a Russian attack had already happened:
30 Israeli, Foreign Intelligence Officers Killed in Russia’s Caliber Missile Attack in Aleppo:
“The Russian warships fired three Caliber missiles at the foreign officers’ coordination operations room in Dar Ezza region in the Western part of Aleppo near Sam’an mountain, killing 30 Israeli and western officers,” the Arabic-language service of Russia’s Sputnik news agency quoted battlefield source in Aleppo as saying on Wednesday. The operations room was located in the Western part of Aleppo province in the middle of sky-high Sam’an mountain and old caves. The region is deep into a chain of mountains. Several US, Turkish, Saudi, Qatari and British officers were also killed along with the Israeli officers. The foreign officers who were killed in the Aleppo operations room were directing the terrorists’ attacks in Aleppo and Idlib.”
Whether this really happened or whether the Russians are leaking such stories to indicate that this could happen, the fact remains that US forces in Syria could become an obvious target for Russian retaliation, whether by cruise missile, gravity bombs or direct action operation by Russian special forces. The US also has several covert military installations in Syria, including at least one airfield with V-22 Osprey multi-mission tiltrotor aircraft.
