Israel. Why?

Wikileaks' publication of US diplomatic cables could have sparked a fresh controversy between Israel and its most important ally after a year of strained relations.

But instead, Wikileaks' release of the documents on Sunday has proved to be something of a public relations coup for Israel: on-the-record confirmation that its Arab neighbors are just as frightened as the Jewish state by a nuclear Iran. The cables confirmed previous anonymous reports that Israel has quiet partners in the region pushing the US to take bolder steps to stop what they consider an existential threat.

Iran is an "existential threat." Iran as being and nothingness. To be or not be Iran.
For it [Israel] has experienced the fear of death, the absolute Lord [Iran]. In that experience it has been quite unmanned, has trembled in every fibre of its being, and everything solid and stable has been shaken to its foundations.
