Mission creep is the expansion of a project or mission beyond its original goals, often after initial successes. Mission creep is usually considered undesirable due to the dangerous path of each success breeding more ambitious attempts, only stopping when a final, often catastrophic, failure occurs. The term was originally applied exclusively to military operations, but has recently been applied to many different fields. The phrase first appeared in articles concerning the United Nations peacekeeping mission during the Somali Civil War in the Washington Post on April 15, 1993 and in the New York Times on October 10, 1993.
Somali Civil War 
The first two articles to use the term in the Washington Post were both by columnist Jim Hoagland ("Prepared for Non-Combat", April 15, 1993 and Beware 'mission creep' In Somalia, July 20, 1993). The New York Times used the term for the first time in an article by correspondent John H. Cushman, Jr. written after the October 4, 1993 firefight in the capital of Somalia, Mogadishu, in which 18 American military personnel were killed.
The U.S. and later UN Mission in Somalia (Restore Hope) would seem to be the classic example of mission creep. Begun in late 1992 as a U.S. humanitarian relief operation in the final months of the George H. W. Bush administration, the intervention was converted to a U.N. operation on June 4, 1993. While the initial Bush administration justification for entering Somalia focused on "humanitarian assistance," realities on the ground helped drive ever growing requirements. On June 5, 1993, Somali warlord Mohamed Farrah Aidid's clan forces killed 23 Pakistani peacekeepers who were part of the UNISOM II mission. This battle led to a UN Security Council decision seeking to capture those responsible for the deaths of the Pakistani peacekeepers. Along with growing objectives seeking longer term stability (rather than short-term humanitarian assistance), the search for Aidid fostered a more confrontational environment through summer 1993. In October 1993, 18 American soldiers died in the Battle of Mogadishu. This incident led to a much more defensive U.S. and UN presence in Somalia. U.S. forces withdrew in early 1994 and all UN forces were withdrawn at late February, early March 1995 via Operation United Shield.
Libyan Civil War 
The phrase has been used again frequently with regard to the multi-state coalition's intervention in the 2011 Libyan Civil War. It appeared as early as March 7, 2011, when a Reuters article wrote that Britain's vision of a no-fly zone over the country would be "likely to experience 'mission creep' and move closer to U.S. thinking on the need to target (Libyan leader) Gaddafi's defenses". On March 31, 2011, with the campaign in its second week, U.S. Defense Secretary Robert Gates told a Senate hearing that "I am preoccupied with avoiding mission creep and avoiding having an open-ended, very large-scale American commitment in this respect". A joint article written by the leaders of the United Kingdom, United States and France that appeared on April 14, 2011 stated that Gaddafi "must go, and for good". Some British MPs warned that this statement represented mission creep, as it exceeded the parameters of UN Resolution 1973, which stressed humanitarian objectives and did not include regime change as a stated goal.
Retroactive applications of the term 
Although the term mission creep is a 1990s invention, examples can be observed throughout military history.
Another early example of mission creep is the Korean War.[dead link] It began as an attempt to save South Korea from invasion by the North, but after that initial success expanded to an attempt to reunite the peninsula, a goal that eventually proved unattainable. That attempt resulted in a long and costly retreat through North Korea after the intervention of the Chinese. NBC reporter David Gregory has cited the Vietnam War as an important example of mission creep, defining it as "the idea of, you know, gradually surging up forces, having nation-building goals, and running into challenges all along the way."
In 1956 Aneurin Bevan, politician and architect of Britain's National Health Service, gave a speech before the House of Commons on December 5th against Britain's mission creep in the Suez war against Egypt. "I have been looking through the various objectives and reasons that the government have given to the House of Commons for making war on Egypt, and it really is desirable that when a nation makes war upon another nation it should be quite clear why it does so. It should not keep changing the reasons as time goes on." The speech was considered one of the 14 greatest speeches of the 20th century by The Guardian, along with speeches by Churchill, Kennedy and Mandela. Eventually the United States, the Soviet Union and the United Nations played major roles in forcing Britain, France and Israel to withdraw from Egypt.
Non-military examples 
Another example of a non-military use of the term mission creep is in connection with "fusion centers." Fusion centers have been created as a counter-terrorism measure in the wake of the September 11 attacks in 2001 via the Department of Homeland Security. Essentially, fusion centers involve the collaboration and sharing of information across various levels of government and private sector entities connected with Americas's critical infrastructures. There are currently, as of 2011, 72 fusion centers in the U.S. A criticism of fusion centers is mission creep in which information being shared begins to include crimes other than terrorism that increases the risk that fusion centers may violate the civil rights of American citizens.
