Why does the West want a compliant Iran? Here's one reason of many: Schroeder says Nabucco needs Iran gas
"Germany's ex-chancellor Gerhard Schroeder has called on the European countries to rely on Iran as a source of natural gas for the Nabucco pipeline.

After years of stalling, Turkey, Bulgaria, Romania, Hungary and Austria finally sealed the Nabucco contract on July 13, as the first step toward building the pipeline that is to break Russia's near-monopoly on Europe's gas supply by transferring Caspian gas to the heart of the continent in Austria.

As they inked the agreement in the absence of Iran, Turkish Prime Minister Tayyip Erdogan said Iran should be brought into the project “when conditions allow.”

After the European partners signed the deal, the US lobbied against Iran joining as a supplier."-PressTV
