There has for some time been a certain suspicion in the Islamic blogosphere that Wikileaks is a tool of Israel, and the latest batch of documents has fanned the flames of that suspicion.
One example here.
Personally, I'm unconvinced, but wavering. The evidence in favor of this theory is all circumstantial. Basically the argument revolves around the fact that there is nothing damaging to Israel yet to be found in any Wikileaks data dump, and that the overall effect of the leaks would seem to work in Israel's favor.
The other point advanced in favor of this argument is that Julian Assange has allegedly dismissed all suspicion of any 9-11 cover up, and some feel his credibility is fatally wounded by that dismissal.
There are replies one could make to these arguments in favor, but they all seem a bit weak and contrived. Correlation does not necessarily imply causation, but generally there's some connection, and statistics be damned.
On this issue, I honestly have no idea what to think. But I will observe that it has been a while since anyone accused me of not being sufficiently cynical about the ways of the world.
