U.S. officials say they believe the death of Osama bin Laden has pushed al Qaeda to near collapse. That is good news -- but not the whole story, as CBS News correspondent Bob Orr reports.
If there is an "American" wing to al Qaeda, it's in Somalia. Since 2007, about 40 young American men have traveled there to join the jihadists of al-Shabaab, recruited by Omar Hammami, another U.S.-born terrorist. Fifteen of the American fighters have been killed and four more have been captured.
But where are the others, asks New York Congressman Peter King.
"As many as two dozen Muslim-Americans with al-Shabaab -- who in many cases were trained by top al Qaeda leaders -- remain unaccounted for," he said.
An even bigger immediate threat to the U.S. homeland is coming from the Yemen-based terror group al Qaeda in the Arabian Peninsula. It has mounted two failed attacks in the past 19 months with the underwear bomb and explosives on cargo jets.
In a new audio warning, Qaeda in the Arabian Peninsula's chief Abu al-Wuhayshi is threatening to strike again. Wuhayshi is also pledging loyalty to al Qaeda commander Ayman al-Zawahiri.
But in truth, U.S. officials are now more worried about the franchises than al Qaeda's core. Relentless drone strikes in Pakistan and the death of Osama bin Laden have the original terror group on the ropes.
"The reality though is that in its wake comes a more fractured regionalized movement that still presents real terrorist danger and threats to the United States," said CBS News national security analyst Juan Zarate. "But it is different from what we've seen."
U.S. officials are not ready to celebrate any victory over al Qaeda. The threat is morphing and not going away.
