What explains the rise of ISIS? Why did they want to go further than al-Qaeda? How did they use terrorism to further their goals?
ISIS rose due to the United States' intervention in Iraq because it created a convincing reason for mobilizing insurgency, which gradually developed into ISIS.
ISIS wanted to go further than Alqaeda because they believed that they are chosen to punish Rome and other nations during the day of judgment.
ISIS used terrorism to attack nations such as America so that they would stop fighting the group.
