The context from the Palestinian side is quite different and comparing the two is flawed for many reasons:

There was never a consensus on the Oslo accords from both sides. While the Israeli Labor pushed for the process, the Likud and the rest of right wingers worked thoroughly to undermine it. And on the Palestinian side, the OLP, essentially Fatah, went on to accept terms every other Palestinian faction refused to adhere to (demilitarized state, practically land-locked on a mozaic of patches that amounts to a fraction of the country's total area and surrounded everywhere with ever-increasing Israeli settlement projects.

That effectively weakened Fatah's position which essentially morphed into a caretaker on behalf of the Israelis for the day-to-day. And the resistance weight shifted from secular factions to the Hamas.
