Her book traces the involvement of Iraq in the first WTC bombing. She explains how the NYC Police and Attorney's office were pursuing the Iraqi angle until the Clinton Administration shut them down.
She explains that up until 1994, the US believed all terrorism was state sponsored, but because the Clinton Administration would not confront Iraq, they changed terrorism into shadowy figures without any state ties.
She also looks into the Khobar Towers and the embassy bombings and shows the link between Iraq and Al Qu'eda. She says that Saudi and Kuwaiti intelligence told the Clinton administration that Al Qu'eda was fronting for Iraq and the Mossad backed them up... but the Clinton administration didn't want to hear it and so ignored it.
Like I said, the book is very well researched.
