This crisis will only end if there is peace and everyone will stop blaming each other. First, the UN and esp the Arab and Gulf states and Russia need to work together to obliterate ISIS and then they can deal with Assad and what is left of Syria. I find it odd, that the UN worked together to get rid of Milosevic but have done nothing to get rid of Isis, which is 10 fold more horrific. After this, Syria needs to be partitioned off just like Bosnia was to end the war there, with each sect getting a different partition, but still under the country of Syria as obviously these people cannot get along.
