The "3P" paradigm – prevention, protection, and prosecution – continues to serve as the fundamental international framework used by the United States and the world to combat contemporary forms of slavery. The U.S. Department of State's Office to Monitor and Combat Trafficking in Persons employs diplomatic, economic, political, legal, and cultural tools to advance the "3P" paradigm worldwide. Announced by Secretary of State Hillary Rodham Clinton in 2009, the "fourth P" – partnership – serves as a pathway to progress in the effort against modern slavery. The paradigm is outlined in the United Nation's (UN) trafficking in persons protocol and the United States' Trafficking Victims Protection Act (TVPA).
