Austere Challenge 12 was supposed to take place at the end of April and was going be the largest joint U.S./Israeli war game in history. The game was two years in the planning and was massive in size and scope and thousands of American military personnel and various U.S. missile defense systems were going to be deployed in Israel. To quote the Jerusalem Post “The drill was supposed to include the simulation of various missile defense scenarios with the objective of creating a high level of interoperability so that, if needed, US missile defense systems would be able to deploy in Israel and work with local defense systems during a future conflict.”
