All of the groups in this region (and the world at large), government or not, are extremely evil and capable of unimaginable violence. You cannot pick and choose to ignore the evils of one group because it is politically beneficial. Well, you can, but that's hypocritical.
The point is that if your goal is to keep the region stable, maximize your influence, and minimize deaths, you have to treat everyone according to the leverage they have. Not the leverage you wish they had based on your moral judgements.
The US media overwhelmingly portrays this as Israel being picked on "for no reason" by all of the savages in the region, and this hampers people in the west's ability to look at the situation objectively.
