Neither Israel nor the US is willing to let things reach that point.
They have recruited major allies to the fight, including Australia, Canada, Brazil and several European states. Germany, the court's second largest donor, has threatened to revoke its contributions if the ICC proceeds.
Maurice Hirsch, a former legal adviser to the Israeli army, wrote a column last month in Israel Hayom, a newspaper widely seen as Netanyahu's mouthpiece, accusing Bensouda of being a "hapless pawn of Palestinian terrorists".
He suggested that other states threaten to pull their contributions, deny ICC staff the travel visas necessary for their investigations and even quit the court.
That would destroy any possibility of enforcing international law - an outcome that would delight both Israel and the US.
It would render ICC little more than a dead letter, just as Israel, backed by the US, prepares to press ahead with the West Bank's annexation.
