someone must do something urgent about ISIS

I was watching cnn fareed zakaria program where she was interviewing zainab Bangura who is Special Representative of the United Nations Secretary General on Sexual Violence in Conflict

according to her,a real women auction is happening in Isis territories ,according to her report there are 3 levels of of leadership namely
fighters ,who report to Emir who report to Sheik,according to report,women are stripped in an open market where men bargain those women as if they are cows,
the best and youngest are sent to sheiks and some of those girls are as young as 12 and below,in one instance a girl was sold for a packet of cigaret after "serious negation"imagine a naked woman in an open market and men old to be her grand father talking how cheap she is,some saying she has small tits sagging backs???
the report also suggest that the fighters are forcing the ladies to get pregnant with a target of producing forth a generation of their sons who are in their image and who will follow their actions,if this report and true and the actual truth is that Isis is growing in number and in territory,if the world wont crash them now,then osama was a joke

lastly i have two questions

1,is there any possibility that this is the old Taliban in a new outfit???
2,since these people do not have a factory where they manufacture guns bullets ,rpg etc who is providing them with weapons and what benefit are they getting back
