House of Bush, House of Saud

House of Bush, House of Saud: The Secret Relationship Between the World's Two Most Powerful Dynasties is a 2004 book by Craig Unger that explores the relationship between the Saudi Royal Family and the Bush extended political family. Unger asserts that the groundwork for today's terrorist movements and the modern wars that have sprung up about them was unintentionally laid more than 30 years ago with a series of business deals between the ruling Saudis and the powerful Bush family. The Saudis received investments and military protection in exchange for cooperation on lucrative oil deals. The author claims that the result has been a shady alliance between "the world's two most powerful dynasties." Unger writes, "Never before has an American president been so closely tied to a foreign power that harbors and supports our country's mortal enemies."

Research conducted for this book backs up claims made in controversial documentary filmmaker Michael Moore's 2004 picture Fahrenheit 9/11.
