Tom Segev, an Israeli historian, author and journalist. He is associated with Israel's New Historians, a group challenging many of the country's traditional narratives
Segev said in an equally interesting 2012 article, also came out against the various theories. “None of the four people who could have ordered an attack on an American ship - Prime Minister Levi Eshkol, Mossad chief Meir Amit, Defense Minister Moshe Dayan and Chief of Staff Yitzhak Rabin - was daring and crazy to that extent,”
"There is no proof that Israel attacked the ship maliciously. No motive for this has been proven. None of the four people who could have ordered an attack on an American ship - Prime Minister Levi Eshkol, Mossad chief Meir Amit, Defense Minister Moshe Dayan and Chief of Staff Yitzhak Rabin - was daring and crazy to that extent.
"Over the years, various pieces of evidence have emerged that seem to support Israel's claim that the ship was fired on by mistake. However, a number of questions still hover over the affair, and these nourish the conspiracy theories."
No motive for Israel's attack has been proven because no US governmental entity has ever undertaken an investigation into culpability for the assault. A US Navy Court of Inquiry investigated seamanship issues, but no agency has ever conducted a fact finding inquiry into why Israel launched the deadly aggression.
