UN should start war against ISIS

I saw a documentary in Television about ISIS starting time and it's developing stage till today. I saw it's all about killing innocent people and rape innocent woman who are not participate in the war against themselves. They make women their sex slave and they give validate it by the saying of religion of Islam. They want to their religious pattern Ohabi Salafi is the only the right of within Islam beside any other religious pattern is wrong and have not about religious validation on the Islmic holy book.

I am a Muslim and i read lot about different kind of Islamic book for my religious purpose and eagerness but i find that what ISIS day it's not at all eligible with Islam what ISIS do by their work. In this age they start slavery system by the people who are they defeat war against them. How it is possible! How people who are supporter of humanity can accept this. I think Muslim powerful state like Saudi Arabia and Jews state also play a huge supporting role with them.

The question is UN which is the organization of worlds human being representative to protect the human right what's their role against ISIS? Why they do not deploy soldiers against ISIS to protect the innocent people rights. Who will do this job to protect the life security and protect women to being raped. Are we going to middle age? So it is high time to do this otherwise the world will not be safe for any one.
