How Much Did WikiLeaks Damage U.S. National Security?

To its supporters, the WikiLeaks disclosures have revealed a wealth of important information that the U.S. government wanted to keep hidden, particularly in the wars in Iraq and Afghanistan.

This included abuses by the military and a video that showed a U.S. helicopter attack in Iraq on suspected militants. Those killed turned out to be unarmed civilians and journalists.

WikiLeaks founder Julian Assange, now under arrest in Britain, has often argued that no one has been harmed by the WikiLeaks disclosures.

But many in the national security community say the leaks were harmful to a broad range of people. However, they generally say the damage was limited and has faded since the first big WikiLeaks dump in 2010, which included hundreds of thousands of classified documents from the U.S. military and the State Department.
