It is an old news : the Israelis are scared on the health of Mubarak but will their prayers to the rais be accepted !!? They know that he will not live forever or even worse he could be an ex-president by a revolution or a coup.
The Iranian example of the Shah is hunting the Israelis and they believe that the American administration will stop any one they dislike from taking over the throne of Egypt, I am afraid it is not up to them nor to the Americans especially now.
Let the Israeli government fears the Muslim brotherhood despite they likely will not rule insh Allah for many reasons the brotherhood knows very well. I just hope both the Americans and the Israelis back off from what ever is going to happen in Egypt because the Egyptians are reaching to a point of no return in their anger according to many indicators.
Israel claims to be the oasis of ultimate democracy in the Middle East where as it does not wish for Southern neighbor to have a real democracy , is not this selfishness !!??
By the way did you notice the part where it says Bibi does not want to remind the world that Mubarak is participating willingly in the siege of Gaza !!
