How could the collapse of the Assad regime in Syria affect Russia's energy influence in Europe?

The fall of the Assad regime opens the path for the Qatar-Turkey gas pipeline project that was previously blocked. This pipeline would connect Qatar's massive South Pars North Dome gas field—the largest natural gas field in the world—through Saudi Arabia, Jordan, and Syria to Turkey and onward to European markets. This development could dramatically undermine Russia's energy leverage over Europe, as Qatar's reserves are so enormous they could theoretically supply all of Europe's gas needs for an entire century. The Turkish Energy Minister suggested reviving this pipeline project just days after Assad fled. If completed, it would allow Europe to completely end its dependence on Russian gas, effectively eliminating the Kremlin's remaining energy leverage in the region.
