As with Arafat, Israel's first considerations would be: with him gone, who then will fill the vacuum....and how then will he prove his worthiness toi the others.
That is a liberal view point. What is the position Isreal has had since 1948? Their potential elimination from the planet, genocide, and the loss of their identity. They knew from the beginning of this political evolution, that their movement into the forefront of world politics would end up as an up hill battle.
We see Omert as a disfunctional leader, barely surviving a potential coup, by his own people after almost selling the Isrealis down the river and acquiescing to the demands of the Arabs.
In the recent history of these people, when has appeasement been in their dialect?
Not until recently.
someone will always step into the fray, and pose a problem to them. Such has been the way of the Jew from the beginning of their religion over the numerous millenia of their existance.
By the way, in my unhumble opinion - you're going to love this - Arabs and Persians are not worthy of anything.
