According to this data, there were more Jewish acts of terrorism within the United States than Islamic (7% vs 6%). These radical Jews committed acts of terrorism in the name of their religion. These were not terrorists who happened to be Jews; rather, they were extremist Jews who committed acts of terrorism based on their religious passions, just like Al-Qaeda and company.
