Hart is the author of several books including a 1984 biography of Yasser Arafat, Terrorism or Freedom Fighters: Yasser Arafat and the PLO. More recently he has completed the trilogy Zionism: The Real Enemy of the Jews.
I defend his individual right to personal opinion. Sadly, he never produced any facts besides parroting controlled demolition theory. Hart and Alex Jones use the same "facts" (speculations) but one blames Mossad, another CIA.
Regarding the purpose of the 9/11 attacks, Hart stated that: “My guess is that at an early point they [Mossad] said to the bad guys in the CIA – hey this operation’s running what do we do, and the zionists and the neo-cons said let’s use it.”
Guess is enough to start anti-Zionist whining. Guess, speculation, and emotions are the only tool of cognition for some folks and that results in certainty of their knowledge.
