Clear warnings by the IDF "We will kill civilians if they stay there" - it says it all really.

But to stay on the Yazidi and IS - one swallow does not make a summer and as of a little while ago "shock and awe" is going to be just as useful as it was in Vietnam. IS are detestable maniacs but believing that they will run rather than hide in plain sight is unrealistic. Do you really believe that depopulating most of the middle east is acceptable or a long-term solution? How well did it work for the Romans?
