But in reality Yom Kippur War was just a continuation of the previous one: Six Days War. Everyone in Israel knew that if Sinai and Golan weren't returned by some sort of agreement, there would be another war. The moment Egypt got what it wanted - peace agreement which included Sinai - war was not in their minds again. Today, even if Syria and Hezbollah were to attack Israel, Egypt most certanly wouldn't join them. If Syria would get Golan by some agreement, they would also lose any desire for war. That would also mean that Hezbollah would lose most of its bite, as well. While in 1948. they all probably thought that they could reach Tel Aviv and destroy Israel, today, situation is different. Even the most fanatical Syrian nationalist knows that Israel is here to stay, and any statements to the contrary are just rhetoric for domestic consumption. Arab pride is a powerful driving force. If they feel slighted, they seek to get even, and won't stop until they feel that slight has been rectified.
