We have to ask ourselves how a group such as Daesh is able to grow so quickly and are so successful in terrorizing the world. Why should we know this? Because there is a root to this branch of Islam and if you do not destroy the root the branches keep coming back and multiplying.
Not one American soldier should put their life on the line to destroy this group. Let the Arabs take care of if within themselves. It will keep them busy and give them a focus for their death wish lifestyle.
