Keith, the objection so many have to the conduct of Israel is not so much their fight against Hamas but their killing of children and non-combatants. Even if Hamas take hostages to use as human shields (it seems more plausible that in a place as densely populated as Gaza it would be difficult for Hamas to put themselves somewhere there were not many children and civilians) you are supposed NOT to kill the hostages. Given that Israel has some of the most sophisticated and accurate weapons in the world it looks as if they are not bothering to try to achieve that end.

Now, back to the Yazidi. Fox is reporting problems (as I predicted in the Caliphate thread) problems with trying to solve the crisis with only air power. The Iraqi army is a broken reed. And Iraq doesn't want to give the Kurds much better arms - because when and if Isis goes away the Kurds will turn those arms on the Iraqi army as part of their demand for Kurdish independence (foolish as current events may seem to make that aspiration).

Ah, yes, the report -   http://www.foxnews.com/politics/2014/08/12/iraq-militants-changing-tactics-complicating-us-airstrike-mission/
