No. The plan is give us 1967 and we will give you peace. Not sure what your information source is.
As for the right for return. We all want to return home. Refugees from 1948 have legal land deeds dating back pre-1948 which Israel doesn't recognize (no surprise).
The right of return mean compensation for such deeds more than anything else. The Jews demand the same of the Swiss, Germans, Austrians, Czechs, etc... today all the time. Its the same. Only propaganda gives it another definition.
As for the blame. Please. Since Islam came to Palestine in the 7th and 8th centuries, Jews and Muslims have been living in peace. Jews would escape Chrisitian Europe to live in Arab Muslim lands from Morocco to Iraq in search of a better life which they got. Then Europe helped create the artificial state of Israel on madate Palestine. The problems started with the mandate policies, the brainchild of Lord Balfour, and got aggravated following the Naqba (creation of Israel). Israel is to blame for our current conundrum.
Golda Meir said "Palestinians, there are no Palestinians". Yes thats a GREAT way to obtain peace.
And you refer to the 90s, where were the Arabs? If the Arab states didn't want peace then the PLO under Arafat would never have been able to return to Tunis with a peace agreement in hand. The PLO's raison d'etre was because of Arab support. Every hear of backroom channels dude?
