"One month after the International Criminal Court (ICC) officially came into existence on July 1, 2002, the President signed legislation that 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 would continue the prohibitions for FY2007."
