"Islamism" has nothing to do with the attack on the Liberty, nor with Captain Boston's allegations of an LBJ-McNamara coverup.
Somehow, I don't think either Admiral Moorer or Captain Boston are on the Al-Qaeda payroll. Captain Boston was most likely incensed that Jay Cristol repeatedly cited him to support the argument that the attack was an accident. Admiral Moorer has been arguing for some time that the attack was deliberate.
Appendix: The disturbing statements of a leading Liberty crewman
James Ennes, perhaps the leading conspiracy proponent among the former Liberty crewmen, who was interviewed extensively by the History Channel, has made extreme anti-Jewish and anti-Israel statements in e-mail discussions on Prodigy. For example, in a message dated June 8, 1992 referring to Jews, Mr. Ennes stated:
... Consider their dilemma: For generations they wanted their own country as a haven from racists. Finally they got it. Gradually they learned that their “leaders” obtained the new country by murdering and frightening away the original owners. Gradually they learned that the new leaders were actually the worst kind of self-centered, amoralistic murderers - worse than the people they sought to flee from.
This was too much of a moral dilemma for many of them. Some drew silent. Others turned against the people who betrayed them and now led their new country. Others pretended that all was well and that the new country was surrounded by extremists and that this condition justified every kind of brutal excess.[sic] And over the years they have instilled this narrow view in their children who now accept it as religious dogma. It is a very sad situation indeed.
Of course, the people that Jews fled from were first and foremost the Nazis, so Mr. Ennes is saying that Israel’s leaders are “amoralistic murderers” who are “worse” than the Nazis.
In another message dated July 22, 1992, Mr. Ennes stated:
... the fact is Israel would have no enemies if they did not constantly raid their neighbors, steal their land, take their water and kill their children.
Mr. Ennes’s statements are nonsense copied directly from his apparent good friends in the pro-Arab propaganda industry. Clearly, if before the attack on the Liberty Mr. Ennes was not an extreme anti-Israel partisan, he has become one since. His allegations concerning the Liberty must be viewed in that unpleasant context.
