I'm going to answer you with my personal experience because I lived in Palestine before the Oslo accords and afterward. I remember when the Palestinian Authority took over Ramallah. I left my medical school in Jordan and I went to celebrate in the streets of Ramallah. That's how the Palestinian people reacted to the peace process.
A year later, Yitzhak Rabin, the Prime Minister of Israel, was assassinated by the right-wing Israeli parties who rule Israel today. This is when we started to see the falling down of this hope and this peace process.
