The American Service-Members’ Protection Act (ASPA, Title 2 of Pub.L. 107–206 (text) (PDF), H.R. 4775, 116 Stat. 820, enacted August 2, 2002) is a United States federal law that aims “to protect United States military personnel and other elected and appointed officials of the United States government against criminal prosecution by an international criminal court to which the United States is not party.” Ma, soprattutto:

“ASPA authorizes the President of the United States to use “all means necessary and appropriate to bring about the release of any U.S. or allied personnel being detained or imprisoned by, on behalf of, or at the request of the International Criminal Court”. This authorization has led the act to be nicknamed the “Hague Invasion Act”
Ovviamente: International Criminal Court = Corte Penale Internazionale.
