Its not propaganda.
S-300 has many customers, and they havent complained. Iran had all this while to drop the much delayed S300s RUssia supplied IRan and Iran hasnt complained about them. China hasnt complained about its S-400s, India is excitedly waiting for its own S400s. Whats the issue with S300s and S400s in Syria not firing? Russia is blocking them from firing at Israeli jets! THere is some electronic way that Russia either controls the launches, or interferes with launches/decides if launches will occur in Syria currently. This is the same issue with TUrkey's S400...TUrkey's biggest foolish mistake with buying the S400s is that Russia would have installed backend hacks to either eavesdrop on transmissions, info etc, or control them or be able to interfere with them. Its not magic - its called interference.
Agreed!!!! Its obvious that Russia has told Assad and his army not to make negative or suspicious public statements about the S300s in Syria. Russia is the main puppet master in the SYrian war.
it doesnt sound absurd at all when you accept that Assad wouldnt even BE PRESIDENT(talk less of controlling soldiers or the SAA) without Russian support and help, DESPITE ANY INCONSISTENCIES in Russian support for Assad. in short, beggars cant be chooser,s and thats what your post supports, which is a lie. you live within your current reality. Assad would have been dead or exiled if not for Russia, and Iran, so they can ask anything of him. thats how life goes when you have little leverage.
