ISIS is an international military group which act like terrorists. They first started as al Qaeda in 2004 but once Osama bin Laden was captured and killed they came back as ISIS. ISIS is more brutal and destructive than al Qaeda was. They have killed over 10,000 people in 2014-2015. They have caused a lot of death and destruction to the world. They are the cause of what has happened in paris and a few other places. They are about scaring people and creating terror. ISIS makes their money by oil, they have taken over oil wells and they makes money off that. Also anywhere ISIS has control and people want to do something there they set a tax or a price for them to do that; for example if you want to drive on their highway you pay; you want to have a business in their area you pay a tax. In the past year ISIS has recruited around 30,000 foreigners.
