The changeover ceremony for the position of National Security Advisor was held Sunday, in Prime Minister Binyamin Netanyahu's Jerusalem office. In a clear reference to the Iranian nuclear program, outgoing Advisor Yaakov Amidror said, "It is important to remember that Israel has one clear existential danger and everything must be done to remove it; if possible, by negotiations and if it is not possible by negotiations, then in another way. The second thing is, today the Middle East is a place in motion. There have already been many upheavals and many more are to be expected in the future. This dangerous situation, perhaps the most dangerous in the 40 years in which I have been dealing with these issues, requires much caution and much thought."
