Bullshit...They made it clear they would only accept one state, from the river to the sea, a state without Jews in it.
As you've said (selectively), 'prior to the Oslo Accords', which is of course the last attempt...
Before that all the Palestinians were offered was a situation where the zionist terrorists were rewarded with Palestinian land and Palestinians effectively became a population of mass refugees...
And that land has been gradually further stolen over the years...
The fact that israel then never proceeded along the route laid out in the Oslo Accords and continuing expansion of settlements led to the violence thereafter...
