I just thought the highlighted sentence was a unique way to make the point.
"As you know, I was in Iraq, Jordan, Israel, France and England on my last visit. And a couple of days ago, as you probably know, an audiotape -- actually it was last week -- an audiotape was released where bin Laden said, and I have to quote bin Laden, ... 'the nearest field to support our people in Palestine is the Iraqi field.' He urged Palestinians and people of Syria, Lebanon, Jordan and Saudi Arabia to quote 'help in support of their mujahedeen brothers in Iraq, which is the greatest opportunity and the biggest task.' Now my friends, for the first time I have seen Osama bin Laden and General Petraeus in agreement, and that is, the central battleground in the battle against al Qaeda is in Iraq today. And that's what bin Laden is saying and that's what General Petraeus is saying and that's what I'm saying, my friends, and my Democrat opponents who want to pull out of Iraq refuse to understand what's being said and what's happening, and that is, the central battleground is Iraq in this struggle against radical Islamic extremism."
