Israel is damned if they do, damned if they don't. If they sit on their hands, they're still hated and rockets are still fired into the region. If they attack and do things their way, they face an investigation for war crimes on top of increased isolation. There really is no right answer here. But if they're going to be condemned or attacked no matter what they do, they might as well just say "**** it" and annihilate every living, breathing thing in that entire region. Sounds bad, but that might be the only way to obtain peace.
