The United States vs. WikiLeaks
WikiLeaks, an online document archive for classified information, has been on the U.S. government's radar since at least 2008, when the U.S. Army and Counterintelligence center published a report outlining the Web site's threat to national security. The site didn't start garnering serious attention from both the government and the public at large, however, until it released more than 92,000 classified documents related to the war in Afghanistan, some of which showed that the Pakistani government had been working with the Taliban against in the United States. The massive leaks have led to hawkish pundits such as the American Enterprise Institute's Marc Thiessen to call for using "intelligence and military assets" to bring WikiLeaks down.
Winner: WikiLeaks so far. All bets are off if Obama takes Thiessen's advice and starts launching predator drones at WikiLeaks servers, however.
