Sure, Israel got letters like this all the time. But October 1968 was less than a year after the Khartoum Conference, in which the Arab League spurned Israel's offer of the territories, saying No Peace. No Recognition. No Negotiations.
They had just offered all the land back and gotten a big fat NO. Khartoum was the high point of Arab intransigence. Who were the Israelis supposed to be flexible with, a brick wall? This letter was an effort to score points over the USSR, who were the only ones who had influence over the Arabs.
There was no Israeli offer of returning the conquered territories. And Nadine knows it. After the 1967 war, the Arabs wanted to settle a peace deal with Israel quickly. Israel refused. The Israeli intransigence led to Khartoum, not the other way around (as Nadine claims). And it is revealing that the countries which were attacked (the Arabs) are supposed to keep their heads bowed when facing the hostile aggressor (Israel). Was Czechoslovakia asked to show conciliation to Nazi Germany in 1938?
Note that, at the time of Khartoum, Marshall Tito formulated a plan calling for Israeli withdrawal from the conquered territories, including full demilitarization and other security guarantees in these territories, and and "end ot the call for an Arab state of Palestine". Egypt and Jordan agreed, Israel rejected it.
The definitive text on the peace process between 1967 and 1973 is Finkelstein's "Image & Reality". But, you don't need to get into these nitty-gritty details. All you need to do is look at 1971, when Egypt offered Israel a full peace treaty, Israel recognized it as a valid offer, and Israel rejected it on the grounds that they were in a position of strength. In 1976, this offer was expanded to Syria, Egypt, the PLO, etc. Again, Israel rejected it (angrily). This has been on the table continuously for the past 3 decades, and it still is.
Your website doesn't mention either 1976 nor 1971. So, I would not consider it a useful resource.
