The paeace treaty or other treaty obligations made by Egypt will not be abrogated or modified at this time. There is no need, the government of Egypt has enough on its plate, although the 'siege' of Gaza from the Egyptian side will probably come to a soon, and ignominous end. As to the future, although Egypt will not abrogate the 'peace', I think such a peace will get a lot colder unless Israel begins to negotiate in good faith with the Palestinians. That is the open sore in the relationship. That means that Israel must stop the settlements and occupation. Egypt, rather than always placating the US and Israel and acceding to all of their wishes and demands, will begin a far more independent foreign policy. If Israel is wise, which I doubt for I have seen no evidence of wisdom in its policies, its belligerent foreign policies must be muted if not ended entirely. Any military moves against the Palestinians, whether in Gaza or the West Bank, will be viewed entirely differently by any new Egyptian government, not to mention any military action against Lebanon, Syria or Jordan. The ball is in your court, but I have seen Israel fumble and arrogantly reject such opportunities since the Arab League proposition.
