I can't.
Yeah, I dismissed the view that the 9-11 attacks were a Mossad operation, coordinated with the CIA, just about as unceremoniously.
The reason many of us dismissed this is because it has never been presented with one single shred of serious positive evidence. Just speculation, mystery-mongering about unmysterious events, and a deep desire to believe the worst of Israel.
The reason many of us dismissed it vociferously is because posters like you have grabbed it with both hands and waved it around from the start, like you do any number of other fairy tales in which Israel plays the heavy. And, granted that our support for Israel could sway us, we know that your hate has blinded you in both eyes.
This is the point in the script at which you fire off a wounded reply saying that you don't hate Israel, you're just being attacked because you put America's interests above those of a foreign country, dah dah dah dah. You needn't bother as far as I'm concerned. Save it for someone who might believe it.
