Here is Unger's response to Isikoff's point that in Unger's opinon the (the one YOU claim is "what is important"):

7) In the same article, Isikoff tries to pit me against Michael Moore by asserting that my book, unlike the movie, concludes that the role of James Bath, a Texas businessman who represented Saudis and was close to George W. Bush, was not terribly significant. Isikoff writes,"The movie—which relied heavily on Unger's book—fails to note the author's conclusion about what to make of the supposed Bin Laden-Bath-Bush nexus: that it may not mean anything."

Isikoff is wrong again. It is true that no conclusive evidence has yet answered the specific question of whether or not bin Laden money actually went from the bin Ladens to Bath and then into George W. Bush's first oil company, Arbusto. But beyond that unresolved issue, the bin Laden-Bath-Bush nexus is crucial to the birth of the Bush-Saudi relationship. Even if bin Laden money did not go into Arbusto, Bath introduced Salem bin Laden and his good friend Khalid bin Mahfouz to Texas. A host of contacts between them and the House of Bush ensued. Bin Mahfouz shared financial interests with James Baker. His associates bailed out Harken Energy, where George W. Bush made his first fortune. Money from both the bin Ladens and the bin Mahfouzes ended up in Carlyle. This relationship is what House of Bush is about.
