al Qaeda's Resurgency

They're back:

Al Qaeda is reinvigorating its operations from havens on the Afghan-Pakistani border and poses a growing challenge to U.S. interests in both Iraq and Afghanistan, American intelligence officials said on Wednesday.

Back to square one:

"The loss of a series of Al Qaeda leaders since 9/11 has been substantial. But it's also been mitigated by what is, frankly, a pretty deep bench of low-ranking personnel capable of stepping up to assume leadership positions," Hayden said.

Proof One:

Despite the death of Abu Musab al-Zarqawi, the al Qaeda leader in Iraq, the two intelligence officials said the group remained a leading actor in that country's sectarian violence, which was likely only to increase.

Washington is clueless as to why they can't defeat al Qaeda:

Hayden claimed success at dismantling the hierarchy that orchestrated the September 11 attacks, but said Washington only partly understands links between regional militant groups and al Qaeda and is just beginning to dissect al Qaeda's effect on so-called home-grown cells inspired by its rhetoric.

Many of Qaeda's recruits are coming from Pakistan:

Al Qaeda continues to be able to recruit young Muslims willing to sacrifice themselves to attack American and Western targets.

And as ABC News found, much of that recruiting is taking place in Pakistan
