It's not isolated, folks
Lest you think the despicable Van Jones' signing of a petition supporting 9/11 conspiracy theorists was his his only anti-American take on 9/11...uhh, no. He was publicly blaming the US on 9/12/01:
A recurring theme of the speakers was the brutal violence committed by or supported by the United States government on a daily basis. "The bombs the government drops in Iraq are the bombs that blew up in New York City," said Van Jones, director of the Ella Baker Center for Human Rights, who also warned against forthcoming violence by the Bush Administration. "The US cannot bomb its way out of this one. Safety at home requires justice abroad."
