You missed the point. If WW3 in planned by those who profit from war, Syria is just the proxy state through which it may begin. It's nothing to do with the domestic affairs of Syria.

There are more interests involved in world politics than just military industrial complexes. WW3 didn't happen at the height of Cold War, when every social, political and economic problem you can reasonably conceive existed and typically at a higher magnitude. And with the baseline adversity back in the day there wasn't any need for a contrived pretext even.
