Besides seeking revenge, Iran’s goal for engineering high-profile attacks in the West would be to turn populations against their governments so that they push policy makers to bring the conflict to an end. Terrorist attacks in Western cities could become a pressure point, making the U.S. and its allies directly feel the pain of this war. At this stage, Iran has very little to lose, and might be willing to take more extreme actions than it has in the past. The U.S. and its allies must remain vigilant and prepare for the possibility of violence on their shores.
