Without Julian Assange, the US cable leaks would have been released un-cut. The White House needs him far more than he needs them.
Together with his media partners, he is the only thing protecting the US from its own leakages. Which makes the ridiculous Fatwha against him all the more stupid and vindictive.
Those attacking him now should be very careful. When the revelations emerge which attack their political Bogeymen (the EEC, Walmart, Wall Street) they will have to perform a hand-brake turn of Essex delinquent proportions, and be revealed as stupid and vindictive too.
