By GCC I assume you mean Gulf Cooperation Council ? do they hgave Special Forces operating in a place like Syria , I thought they were mostly just political. They certainly would profit from getting sanctions imposed on Syria so there would be a lot of motive for them to create a false flag attack
GCC has something like 350,000 troops, and are operating all over the gulf states. What they do is pretty much under the legacy media radar. Did you happen to watch Trump’s meeting with the Emir of Qatar? Watch it. Remember MbS was just over visiting too.
