Voters should care about this bill because it clarifies who holds power over international relations and the treatment of foreign individuals within the United States. If this bill becomes law, it would ensure that only the U.S. federal government, and not individual states or cities, makes decisions about cooperating with the International Criminal Court. This means a more unified national approach to foreign policy and international justice matters.

If the bill doesn't pass, there could be a patchwork of different state and local policies regarding ICC requests, potentially leading to inconsistent application of international law within U.S. borders and possible conflicts with federal foreign policy objectives. This bill aims to prevent scenarios where state or local actions could unintentionally undermine U.S. foreign relations or constitutional principles by acting on international warrants without federal oversight.
