Finally got around to watching this behemoth of a Frontline last night, and I'd very highly recommend it. (You can even watch it online, if you're willing to sit in front of your computer for four hours.) It runs from just after September 11th until just before the surge (or what Condoleezza Rice called the "Clear, Hold, Build" strategy, when she proposed it in 2005), and it's fascinating. In case you don't have time to sit through it, though, I've assembled a Cliff's Notes version below:

These people...	...came off as...
Colin Powell, Richard Armitage, Jay Garner	reasonably competent, but out of the loop
Condi Rice, George Tenet, Tommy Franks	semi-willing pawns
Philip Zelikow	having a comically deep voice
Dick Cheney, Donald Rumsfeld, Paul Wolfowitz	scary; crazy (like a fox?)
Cofer Black, Ahmed Chalabi	crazy (like a crazy person)
L. Paul Bremer	borderline developmentally disabled
George W. Bush	a terrible, terrible speaker; not a very good president*

Good times.

* - Had to get his own box, because he is the president. Do not assume that means he didn't fit into any of the other categories.
