Is WikiLeaks Blackmailing the Pentagon?

On the heels of posting a massive Afghan war log, the secret-sharing site WikiLeaks has yet again posted a file to its site—an encrypted file that is larger than all its other files combined, and one that is simply labeled "insurance." Wired magazine speculates that the file may act as insurance in case the site goes down, or something happens to WikiLeaks founder Julian Assange. The file may be a separate Iraq war log cache that U.S. Army intelligence analyst Bradley Manning—who is suspected to have leaked the Afghan war log to Assange—claims to have also handed over to WikiLeaks. The Iraq log purportedly contains information on 500,000 events from the Iraq war between 2004 and 2009. As Pentagon officials condemn the Afghan war log file-dump, it remains to be seen if, or when, the new insurance file will be made public, and what other damaging information the cache actually contains.
