Azerbaijan ships in large quantities of pipeline gas to the EU, and the pipeline goes through Georgia. And back in 2008, there was a conflict between Russia and Georgia. Since the current regime in Georgia is not very hostile to Russia, the chances are very low. But still I won't rule out the possibilities. Nigeria and the Maghreb countries (especially Algeria) are also important sources of gas to the EU, and these countries are politically very volatile. Only stable suppliers are United States, Qatar and Australia.
Exactly, all the alternative sources they have are too risky and unstable. Georgia itself is a complicated situation that at least 3 fractions are fighting each other over power, some are pro-Russia so obviously they will want to prevent such export to EU.
Speaking of Azerbaijan, things are heating up in somewhat of a media blackout. Our armed forces already crossed Aras river while all of a sudden some people in Nakhchivan declared they want to rejoin the motherland.
After the 10-day straight bombardment of the terrorist bases in Northern Iraq the crosshair is now on Baku. We have to wait and see what that leads to.
Any attempts at terrorist attacks (read - Russian) will lead to the inclusion, full-fledged, of the Turkish army. Although Erdogan is trying to play both sides, he will not miss the slightest chance to show Russia its real place in this region. Probably you will not deny that after Russia, having once again pushed the short-sighted Armenia to the conflict, having heard the statement of Turkey, cowardly put its tail between its legs and ran away from the battlefield. Will leave the Armenian unfortunates to die under the blows of the Turkish-Azerbaijani group. The only thing that Russia can try to do is to incite Iran, with its inadequate regime, which is now conducting exercises near the borders with Azerbaijan, to start a conflict there.
Russia will try its favorite methods to prevent alternative gas supplies to the EU. So it will be necessary to expect new terrorist attacks.
