"One month after the International Criminal Court (ICC) officially came into existence on July 1, 2002, the President signed the American Servicemembers' Protection Act (ASPA), which limits U.S. government support and assistance to the ICC; curtails certain military assistance to many countries that have ratified the Rome Statute establishing the ICC; regulates U.S. participation in United Nations (U.N.) peacekeeping missions commenced after July 1, 2003; and, most controversially among European allies, authorizes the President to use 'all means necessary and appropriate to bring about the release' of certain U.S. and allied persons who may be detained or tried by the ICC. The provision withholding military assistance under the programs for Foreign Military Financing (FMF) and International Military Education and Training (IMET) from certain States Parties to the Rome Statute came into effect on July 1, 2003. The 109th Congress reauthorized the Nethercutt Amendment as part of the FY2006 Consolidated Appropriations Act (H.R. 3057/P.L. 109-102). Unless waived by the President, it bars Economic Support Funds (ESF) assistance to countries that have not agreed to protect U.S. citizens from being turned over to the ICC for prosecution. H.R. 5522, as passed by the House of Representatives, would continue the ESF restriction for FY2007. The Senate passed a measure as part of the 2007 National Defense Authorization Act (H.R. 5122, S. 2766) that would modify ASPA to end the ban on IMET assistance. […] This report outlines the main objections the United States has raised with respect to the ICC and analyzes ASPA and other relevant legislation enacted or proposed to regulate U.S. cooperation with the ICC. The report concludes with a discussion of the implications for the United States, as a non-ratifying country, as the ICC begins to take shape, as well as the Administration's efforts to win immunity from the ICC's jurisdiction for Americans. A description of the ICC's background and a more detailed analysis of the ICC organization, jurisdiction, and procedural rules may be found in CRS Report RL31437, 'International Criminal Court: Overview and Selected Legal Issues', by Jennifer K. Elsea."
