Doubtful.
Most of Israel's friends have the same problems they do. Israel has become an expert at dealing with terrorism, and its allies will continue to pursue a relationship with Israel.
This whole thing also reaks of a set up too. There was no reason for Israel to allow entry of that angry mob. The governments who sent their citizens into Israel were totally irresponsible.
As for Israel's position at the bargaining table:
http://en.wikipedia.org/wiki/Taba_summit
They offered the Palestinians virtually everything they wanted: the Gaza strip, east jerusalem, 97% of the West Bank, but were met with a renewed suicide bombing campaign.
Israel not too long ago withdrew every settler it had in the Gaza Strip. The citizens took the opportunity to elect a government dedicated to Israel's destruction that spend the next three years lobbign rockets at Israel.
What incentive does Israel have to return to the table at this point? Any concession they give is turned against them. They withdraw from Lebanon and its a sign of weakness. The UN refusses to disarm Hezbollah like they promissed under the terms of the agreement. They withdraw form Gaza and they end up with their very own terrorist factory in their back yard. They can't invade or even put economic sanctions on Gaza, becasue that becomes "collective punishment".
I'm not trying to make Israel out to be victims, but realistically from their point of view they will need to see that have something to gain from a "peace agreement". If a peace agreement means you back off while the other side rearms, I don't see why they would want to sit down and talk.
