"The Trump Administration recently announced plans to reevaluate the United States' role before the International Court of Justice (ICJ)--commonly called the 'World Court.' This year, Iran and the Palestine Liberation Organization (PLO, designated as 'Palestine' or 'State of Palestine' within the U.N. system) initiated separate proceedings against the United States at the international tribunal. After the ICJ made a preliminary determination, over the United States' objections, that it had jurisdiction to hear Iran's claims, the Trump Administration announced that the United States will withdraw from the treaties on which both the Iran and PLO cases are based. The Administration also stated that it will review all other international agreements 'that may still expose the United States' to ICJ jurisdiction."
