"Evidence linking these Israelis to 9/11 is classified. I cannot tell you about evidence that has been gathered. It's classified information." -- US official quoted in Carl Cameron's Fox News report on the Israeli spy ring and its connections to 9-11.
Israel has a very long history of using false-flag operations to trick other countries into waging war on Israel's enemies. On 9-11, as was the case with the USS Liberty cover-up, the Israelis appear to have the full cooperation of the United States Government!
