I think Israel is reasonably safe in the long run actually, despite the calls of many Islamic militant groups calling for it's 'extermination'.

One should always keep in mind that a grievant party's initial negotiating position is rarely what they eventually will settle for.

Case in point

Tim Sebastian of the BBC, interviewed Khaled Meshaal, the overall head of Hamas on his Hardtalk programme, recently. The complete transcript is on the other side of this link.
Sebastian is known for not pullimg his punches, irrespective of who is sitting across the table from him.
Here is what he got Meshaal to say:

"I have said what Sheikh Ahmed Yassin has said. You have quoted Sheikh Ahmed Yassin. What he said concerning the withdrawal to the '67 borders. If this happened we might have a truce with Israel. We believe in this in Hamas."

If everybody kept to previous agreements and I mean everybody concerned, one might find that a true peace in the Middle East could actually happen.
