As of June 2007, more than 100,000 military and civilian personnel are engaged in UN peacekeeping operations in 15 locations in Africa, Europe, Asia, the Americas, and the Middle East. In 2006, the United States provided the UN with about $1 billion to support peacekeeping operations. Given that thousands of U.S. troops are intensively deployed in combat operations in Iraq and Afghanistan, UN peacekeeping operations are an important element in maintaining a secure international environment. As requested, this testimony discusses (1) the costs of the current UN mission in Haiti compared with the estimated cost of a hypothetical U.S. operation and (2) the strengths and limitations of the United States and the UN in leading peace operations. This testimony is based on our prior report and information we updated for this hearing. To estimate U.S. costs, we developed parameters for a U.S. mission similar to the UN mission in Haiti, which the Joint Staff validated as reasonable. We then applied DOD's official cost estimating model. However, it is uncertain whether the United States would implement an operation in Haiti in the same way as the UN.
