Who Supported Israel as a "Jewish State?

A resolution was adopted in early 1977 and, in part, reads:

"...We call upon these,[Arab countries and Palestinian leaders] as well as other Arab spokesmen to publicly acknowledge...and, further, to clarify, that they recognize Israel's right to exist as a sovereign Jewish state within secure borders.  Such recognition is essential for successful peace negotiations."  

Which organization promoted, as a central element to a future Arab-Israell peace, the demad for recognition of Israel as a "Jewish state"? 

It was pointed out to me to look at the April 1977 issue of Jewish Currents.

On page 13, we read:

and here is the entire page which reveals that it was the radical/progressive Breirah group:

In fact, in testimony before the US Senate Subcommittee, Robert Loeb
Executive Director, Breira said, as per his letter published in June that year,

“Those of us who are willing to speak out . . . in recognition of legitimate Arab national rights alongside Israel, do so as a challenge to the Arab world, and to the Palestinians in particular, to respond in kind, and voice without ambiguity their recognition of legitimate Jewish national rights in Israel.” 

So, Netanyahu was outflanked by the left almost 40 years ago?
