From the article: "Over the years, we came to understand that Pakistan's intelligence service was playing a double game"

Before we went into Iraq it was obvious that Pakistan was far more of a threat and a far greater strategic priority than Iraq was.

Those who claimed that Iraq was the strategic center of the terrorist threat were being stupid, disonest, or both. If I, an average newspaper reader, knew that Pakistan was the major terrorist threat how can Cheney not have known?
