Great reminder of what many of the underlying motivations are for this conflict. But, gas and oil isn't the guiding issue anymore. The Qataris are beaten on that pipeline and have cut deals with Iran to develop the North Pars gas field which they share and to build an alternate pipeline with Iran to serve Europe.
This is why Saudi Arabia went ballistic last year on Qatar, after Qatar bought a stake in Rosneft to ensure it's survival when it became clear to them that Trump would no longer suppor their support of Al-Qaeda in Syria and Assad was likely to stay in power.
What's left of the original plan for Syria is some desperate thrashing around by the Neocons in the U.S. and the their ideological brethren in Israel/SA to limit Iran, humiliate Russia and break up the alliance with China and complicate OBOR.
