We know what happens with peaceful protests, elections, and foreign interference (and more foreign interference), so how can Palestine gain it’s freedom? Any positive ideas are welcome, because this situation is already a humanitarian crisis and is looking bleaker by the day.
Historical references are also valuable in this discussion, like slave revolts or the Warsaw Ghetto Uprising, although hopefully in the case of Palestine a peaceful and successful outcome can be achieved, as opposed to some of the historical events above.
Violence is the only option, even if you don’t like it. Ask Nelson Mandela.
Alternatively, like in Canada, have your people become the majority and give them Independence, and forget about the destruction of the natives.
Liberation will never be given to you by your oppressor.
