Yemen is now considered to be "the greatest external threat facing the U.S. homeland in terms of terrorism," says investigative reporter Jeremy Scahill.

Jeremy Scahill has been investigating Blackwater, a military contractor with a long involvement in the Iraq war. His latest story, published Nov. 23 in The Nation, uncovers the contractor's involvement in a covert program in Pakistan run by the U.S. Joint Special Command.

Blackwater USA is a secretive private army based in North Carolina with a sole owner: Erik Prince, a right-wing Christian multimillionaire. Jeremy Scahill talks about his book Blackwater: The Rise of the World's Most Powerful Mercenary Army.
