There is a theory (a bit "school of schizo" and totally unsubstantiated but kind of interesting) that the sense of urgency from Israel at the moment is because they really believe in the curse of the eighth decade.

In other words it is actually totally irrational and driven by belief in (and attempt to refute) a kind of prophecy.

No idea if that's true or not, but at this point, it wouldn't even surprise me
