Pepe Escobar Asia Times Sep 28, 2012 “Why Qatar wants to invade Syria”
“Sheikh Hamad bin Khalifa al-Thani has the petrodollars to match the swagger of his call at the UN for an Arab coalition of the willing invasion of Syria. The Emir of Qatar's view will go down well in Washington, yet it's clear his real aim is to kill the $10 billion Iran-Iraq-Syria gas pipeline, a deal clinched even as the uprising was underway”

Hi Felix,

Have you cosidered the impact of the historical Tribal ties betweem Qatar and Saudi Arabia? Or the adherence to the common Wahhabism. Even though the strain of Wahhabism in Qatar is less strident than that in Saudi Arabia it remains a common bond.

The effect of these primary bonds, in historical inter-Arab familial, religious and cultural relationships, may be much more sigificant than mere, from an Arab perspective, discordant economic issues.
