I really have no well-formed views on the merits or demerits of Netanyahu's reforms.
What amuses me is the oft repeated notion that the represent an attack on Israeli democracy. Giving the elected government more power to restrain unelected judges is actually more democratic than letting unelected judges restrain the elected government.
It may well represent an assault on the rule of law in Israel, but rule of law and democracy are hardly coextensive. Britain had the rule of law for centuries when the King or Queen and House of Lords still had significant power and the Commons was still elected only by male land-owners. Lots of countries in Africa and South America have democracies (in the sense that the current kleptarchs stood for election) but lack anything like the rule of law.
As an American who likes the anti-democratic features of our Constitution (the Bill of Rights, the Electoral College, the Senate, the Supreme Court), I think the reforms are probably a net negative for Israel. But an attack on democracy? Hardly! they are democracy in action, unrestrained by a written constitution (as we have) or long enough tradition (as Britain has).
