I'd like to add the following..

It seems that corrupt European interests dominate corrupt Western policy this time, for especially the French and British seem eager to intervene.
One of the biggest natural gas fields on earth is located in the Persian Gulf, it is owned by both Qatar and Iran. Russia's Gazprom is Europe's main supplier.
Iran wants a 'shiite' pipeline through Iraq and Syria. (which Europe is not to eager for, they'd rather see Qatar)
Qatar wants it 'sunni', of course, through Saudi Arabia and then Jordan, Syria. Of course Iran, Iraq and Syria are the larger shiite dominated nations, which and enflames the shiite-sunni conflict.
It's just sickening, how tirants throughout history seem to be able to turn centuries' old conflicts into their advantage.
As other commentors have mentioned, other interests have (a lot of)influence as well, however Europe's addicton to natural gas for heating definitively seems to be a key factor.
