In 2003, Katharine Gun, a young specialist working for Britain’s Government Communications Headquarters, exposed a highly confidential memo that revealed the United States’ collaboration with Britain in collecting sensitive information on United Nations Security Council members in order to pressure them into supporting the Iraq invasion. Gun leaked the memo to the press, setting off a chain of events that jeopardized her freedom and safety, but also opened the door to putting the entire legality of the Iraq invasion on trial.
