stan,
when looking at states it's important to look at the cost-benefit ratio on both sides. what advantages would israel gain in making peace with all of those arab states, and what advantages would the arab states gain in making peace with israel?
in egypt's case, america held out the offer of lots and lots of money if they would come to the peace table. was this also the case with the other arab states?
also, the '73 war, both in the way it was going for the arabs at first and also the way the arabs held up the global economy, was such that despite the defeat, they came off feeling stronger/more confident of their own capabilities. that should be factored in.
finally, look what happened to sadat. the arab leaders sure did.
