New National Intelligence Estimate

[Watser?]

There's a new National Intelligence Estimate out today.

Moon of Alabama has some questions:

Today a new National Intelligence Estimate Report says:

Al-Qa'ida is and will remain the most serious terrorist thread to the Homeland, as its central leadership continues to plan high-impact plots

Question: Why does this organisation and its central leadership still exist?

.. we assess that al-Qa'ida will probably seek to leverage the contacts and capabilities of al-Qa'ida in Iraq (AQI), its most visible and capable affiliate and the only one known to have expressed a desire to attack the Homeland ...

Question: AQI didn't exist on 9/11/2001. What did create AQI?

Bonus question: Why is "Homeland" written with a capital "H"?

I have another question: why aren't the media asking these questions?
