The main purpose of this legislation is to clarify that international organizations can be held accountable in U.S. courts for certain acts related to terrorism. Specifically, it aims to remove the legal immunity that these organizations typically enjoy when they are involved in cases of terrorism, allowing victims to seek damages for personal injuries or deaths caused by such acts. Key provisions of the law include a clear exception to the immunity of international organizations in cases where they are accused of involvement in terrorism-related activities.
