Perhaps it's just entropy in the human genome and it's only a matter of time before every human degenerates into a protector of evil.
I think this has a lot to do with US interference. As long as Iran is developing nuclear weapons, the United States has enormous leverage against Israel. I do not believe this anti-settler policy is Israeli in origin, but rather based on the Obama administration’s interests. Israel has no alternative to appease the United States as best they can. Bibi has to walk a tight rope between the weak US foreign policy and the conservative groups in his coalition. As the Iran clock ticks, you will see Bibi’s policy become more hawkish in nature and he will act unilaterally when he needs to.
