Did the FBI actually leak Stratfor e-mails just to bust Julian Assange?

Here's something for you to think about: Was the arrest last week of the five LulzSec members just part of an intermediate stop gap in the pursuit of a far more prominent fugitive, namely Julian Assange, founder of Wikileaks? 

Seeing that Xavier 'Sabu' Monsegur had apparently been working for the FBI for the last couple of months, it isn't too far-fetched to think that the leaks of the Stratfor e-mails given to Wikileaks by Anonymous was nothing more than a tactic to entrap Wikileaks and build a case against Assange - Michael Ratner, president emeritus of the Center for Constitutional Rights certainly thinks so:

"Normally, these releases went straight to the internet, to the likes of "pastebin" or "piratebay" so this handover to WikiLeaks certainly generates suspicion as to whether the FBI might have directed this release," he says.
