Why? There is no reason for the State of Israel for special respect to the Catholic Church. I grew up in a traditional Catholic family used to the incorrigible hatred agains the Jewish people.

Israel has to follow its own security needs first - the Jewish State has no reason to take into account the wishes of one of the most powerful enemies!
