The difficulty that WikiLeaks has, of course, is that we can't go around speculating on who our sources are. That would be irresponsible.

Knowledge has always flowed upwards to bishops and kings, not down to serfs and slaves.

Libya, more than anyone else's war, was Hillary Clinton's war.

The most important publication of WikiLeaks is that it has published more than 10 million documents. The most important single collection of material we have published is the US diplomatic cable series. We started with 251,000 in 2011, but are up to 3 million now and have more coming.
