It is serious given what they have done and particularly given the fact that ISIS is growing exponentially. I remember we got a figure of about 12.000. and then. last week. it was about 20.000. This week. it is estimated that there are over 30.000. They are recruited from all over the world15.000 foreign fighters. 2.000 of whom are westerners who hold passports where there is a visa waiver and they might be able to get into the United States. Some of them are Americans. They are making millions of dollars a day in revenue from oil and kidnapping and so on.
