If as they contend this law was the equivalent of a constitutional amendment they probably should have required a 2/3 vote of the legislature before enacting it. To put something like this forward with barely over 50% supporting it is just asking for trouble. Now it’s raising divisiveness among Israelis at a very inopportune time.
In the Israeli system.. it only takes more than 50% to change the constitution.. the odd thing is that this occurs so rarely it hasn’t been a problem for those who don’t want things to change.
