The Yemen intervention and other recent actions show how concerned the Gulf states are about the Iranian threat, though an even greater challenge may emerge from their severe tactics against domestic dissent.

New allegations by an al-Qaeda prisoner in the United States have revived questions about official Saudi support for 9/11, while at home the kingdom has been re-arresting former al-Qaeda convicts in a new war on terror.

Unlike most Persian Gulf states, the UAE does not need to balance its counterterrorism policies with any delicate ties to Sunni conservatives.

Other Gulf countries joined the fight against terrorism financing once they perceived a real security risk inside their borders, but Qatar's extraordinary financial and political patronage has deterred that threat thus far.

A quick guide to the finances of the Islamic State of Iraq and al-Sham (ISIS), the world's best-funded terrorist group.

In light of issues such as Riyadh's well-known antipathy toward democratic agendas, Washington should take its cue from what the Saudis signal they are willing and politically able to do.

Alarming ISIS gains in Iraq and Syria present a special opportunity for Washington to work with Qatar on enforcing counter-terrorist financing procedures.
