The Cast Against Qatar

In recent months, Qatar's Rolodex of middlemen like Hossam has proved both a blessing and a curse for the United States. On one hand, Washington hasn't shied away from calling on Doha's connections when it needs them: Qatar orchestrated the prisoner swap that saw U.S. soldier Bowe Bergdahl freed in exchange for five Taliban prisoners in Guantánamo Bay. And it ran the negotiations with al-Nusra Front, al Qaeda's affiliate in Syria, that freed American writer Peter Theo Curtis in August. "Done," Qatari intelligence chief Ghanim Khalifa al-Kubaisi reportedly texted a contact -- adding a thumbs-up emoticon -- after the release was completed.

But that same Qatari network has also played a major role in destabilizing nearly every trouble spot in the region and in accelerating the growth of radical and jihadi factions.
