So far, the Israeli’s destroyed the shipment of Russian advanced anti-ship missiles, but in reality, Russia would not let Syria attack a US ship with one of those missiles, just because the US might think it came from a Russian ship. Besides, and Aegis ship is not an easy target for any missile. There are converted boomers (ICBM subs) over there that have upwards of 192 cruise missiles in the tubes. The Syrians aren’t likely to be able to strike a boomer, especially with the likely attack subs with them. Vlad isn’t about to get into a nuclear confrontation over Syria. Most of the initial strikes will be with drones, to take out anti air and anti ship radars. The advanced missiles need shore based, or ship based radar for the initial phase of their flight. Iran is watching closely, and this WMD test, is just that, a test to determine if they can cross the nuclear finish line without any major consequences.
