I'd receommend reading this interesting post from Security Watchtower on al-Qaeda and Iran:
...growing concern in the intelligence community that Iran is strengthening ties with al Qaedaand maintaining some level of operational cooperation with the terrorist organization. A sizeable percentage of al Qaeda's leadership is in fact being harbored by the Iranian regime according to many.
This is more evidence on how this Administration has actually weakened our security position in the world than strengthened it. How might we deal with Iran now? What about North Korea? Was Iraq really the imminent threat? Clearly, this Administration is in its own little world.
