As already reported by another question the Russian state-owned energy company Gazprom has ceased gas deliveries to Poland and Bulgaria. The problem with alternative supplies is that they are few and some were killed in the past like the Nabucco pipeline. If I understood correctly the official reason to kill the project was commercial, but probably there was political pressure on the background. Given the current situation could the project be resurrected?

Here I'll split my question in two separate questions because international the relations of Iran and Azerbaijan are much different and require different answers. In this question I would like to know what are the political obstacles to the project of a gas connection from Azerbaijan and if would be possible legally to reuse some infrastructure built with funding from Russian companies.
