Final answer:
The question appears to confuse NCIC, a U.S. database that all 50 states participate in, with the ICC, related to international law. The Rome Statute of the ICC has over 120 countries as parties, but the U.S. has secured bilateral treaties to prevent prosecution of its citizens by the ICC.
Step-by-step explanation:
The question 'How many states currently participate in NCIC III?' seems to be a misunderstanding. NCIC (National Crime Information Center) is a United States database, and states here refer to the 50 states of the U.S. rather than countries. Every state in the U.S. participates in NCIC. However, the context provided about the Rome Statute and international treaties seems to refer to the International Criminal Court (ICC), which is a separate entity. Over 120 countries, which are often referred to as states in international law, are part of the Rome Statute, the treaty that established the ICC. The U.S. has not ratified this treaty and has sought immunity through bilateral treaties for its citizens.
International law contributes to global governance by providing a framework for state interactions, setting standards for behavior, addressing transnational issues, and attempting to provide some form of accountability for actions that are deemed to contravene international norms, such as war crimes or crimes against humanity. As such, both the NCIC system within the U.S. and international agreements, like the Rome Statute, aim to facilitate cooperation on legal matters, albeit in different contexts and scales.
