Is there an actual coup going on? I can't find any articles on this.
A controversial judiciary bill that was spearheaded by Netenyahu just passed in Israel despite massive opposition to it.
Also, to OP - nothing will work if Israeli ISPs and the Govt actually wanted to implement internal surveillance (which they in fact do in some limited manner).
That said, I doubt such a situation would arise.
A coup is nothing like this.
A soft coup through “patriot act” style legislation
Who elected the Supreme Court in Israel? Nobody. The power will now lie in the hands of the legislature, which is the definition of democracy.
