The Stand with Israel Act would prohibit the United States from providing financial contributions to the United Nations and its affiliated agencies, programs, and funds if those entities take actions that discriminate against Israel, such as expelling it, downgrading its membership status, suspending its membership, or restricting its ability to participate equally with other member nations. The bill amends the United Nations Participation Act of 1945 and would apply to all federal departments and agencies that contribute U.S. funds to the UN system. The legislation does not specify an amount of funding or implementation timeline, but instead creates a conditional restriction on existing UN contributions that would take effect if the specified discriminatory actions occur. This bill would affect U.S. foreign aid and diplomatic relationships with the United Nations by potentially reducing American financial support to the organization. The bill was introduced in November 2024 with support from 33 Senate Republicans.
