It has been much-reported that Muslim Brotherhood spokesman / head of parliamentary foreign relations committee Essam al-Erian threatened to review the peace treaty with Israel should aid be cut. See for instance:
Other Muslim Brotherhood leaders have repeated the argument that a cut in aid could lead them to review the treaty, or that such a cut would be in breach of the treaty.
To my knowledge, this has no basis in law. The MB may want to review the peace treaty, as many others in Egypt want to, in order to renegotiate the degree to which the military can operate in Sinai. There are good reasons to do so in order to gain better control of the Peninsula. But the aid has nothing to do with the treaty. This was confirmed recently by Jimmy Carter when he was in Cairo, and you can check the text of the treaty itself.
Generally speaking, there is a confusion of terms on this issue.
- The 1978 Camp David negotiations led to the drafting of a broad set of principles known as the Accords, that would look at a global solution to the Arab-Israeli crisis, including its Israeli-Palestinian component. While signed by the US, Egypt and Israel, the accords were never implemented, largely because the Israelis did not want them to be.
- The 1979 peace treaty between Israel and Egypt delineated borders, paved the way for the return of the Sinai Peninsula in Egypt, and imposed restrictions on military activity in Egypt. It does not contain any provisions for aid.
- An aid relationship exists between Israel and the US and Egypt and the US (with the latter since 1975). It was informally framed after Camp David as partly a reward for the peace, and partly to ensure that Israel would get proportionally more aid than Egypt and be helped by the US to retain a military edge. These terms were negotiated, and later renegotiated between the militaries and governments of the three countries, but there is nothing in the treaty itself that obliges the US to disburse aid of any kind to either country.
So when the Brothers make threats about a cut in aid leading to the collapse of the treaty, they either don't know what they're talking about or are making baseless threats. And moreover, by linking aid to the treaty, they are in effect suggesting that Egypt's policy towards Israel is indeed up for sale, and that they will gladly take the money to remain quiet on Egypt-Israeli relations. Is this what they meant to say, after having spent much of the last three decades denouncing the treaty and Egypt's slavish acquiescence to pro-Israel US policies?
Enquiring minds want to know.
