Exactly what part of the treaty did Israel breach. The closest Israel has come to breaching the treaty so far is that it has allowed Egyptian troops into Sinai which is supposed to be demilitarized. Israel has not sent troops into Sinai since 1979, it gave back Sharm El Sheik, closed the Yamit settlement. The only territory we didn't return was Gaza and thats because they were smart enough not to want that garbage dump. The people who have been breaking the treaty over the years are Egypt. Israel will not allow the treaty to be renegotiated and Egypt cannot renegotiate it without Israel's consent. We have never been friends but have been able to deal with each other and as far as Israel is concerned its a pitty Mubarak is gone.
