There is exactly enough "law enforcement" to keep up appearances for the international community and the liberals in Tel Aviv who prefer to live in denial.

Yes, threatened to leave on pain of being murdered. The Israeli right understands that Holocaust-style mass extermination is far more trouble than it's worth; you just need to kill enough people to scare away the rest.
