Iran is letting the al Qaeda members loose:
Al-Qaida operatives who have been detained for years in Iran have been making their way quietly in and out of the country, raising the prospect that Iran is loosening its grip on the terror group so it can replenish its ranks, former and current U.S. intelligence officials say.
This movement could indicate that Iran is re-examining its murky relationship with al-Qaida at a time when the U.S. is stepping up drone attacks in Pakistan and weakening the group's leadership. Any influx of manpower could hand al-Qaida a boost in morale and expertise and threaten to disrupt stability in the region.
Why is Iran doing this now?
Is Iran simply trying to bolster an al Qaeda on the ropes from our pressure?
Is Iran seeking to increase the carnage of terrorism to bolster whatever they have in mind, such as a general offensive involving Hezbollah, Hamas, local sleeper agents in Bahrain, Kuwait, Saudi Arabia, and Iraq?
Or is Iran worried about being a target of America over their nuclear programs and doesn't want us to use the presence of al Qaeda as a pretext to strike?
I'm pretty sure we need to know the reason for this action. It is a significant action by Iran.
