U.N. Anti-Terrorism Accountability Act of 2023

This bill requires the U.S. representative at the United Nations to actively work toward expelling Iran from the UN General Assembly and to encourage investigations into Iran's potential violations of the Genocide Convention. It also blocks U.S. funding to the UN agency aiding Palestinian refugees (UNRWA) until two conditions are met: Iran is expelled from the UN and under investigation for genocide. The bill directly affects Iran's international standing and U.S. financial commitments to the UN, tying funding to specific diplomatic outcomes. It does not alter existing U.S. law regarding genocide investigations but mandates specific diplomatic actions and funding restrictions.
