States parties to the Rome Statute of the International Criminal Court

According to the Vienna Convention on the Law of Treaties, a state that has signed but not ratified a treaty is obliged to refrain from ``acts which would defeat the object and purpose'' of the treaty. However, these obligations do not continue if the state has ``made its intention clear not to become a party to the treaty''. Four signatory states (Israel, Russia, Sudan, and the United States) have informed the UN Secretary General that they no longer intend to become parties to the Rome Statute, and as such have no legal obligations arising from their signature.
