You’re viewing this through your (probably) western eyes.
The population has been radicalized for years now (see youtu.be/W3jHj93JFMQ), and is being controlled by a terrorist organization with a mission of creating an Islamic State in the region, the Palestinian cause is just an excuse it uses.
Coming from outside, not knowing the full history of the region, and saying “ok kids, stop fighting and behave like an adult” when in reality one kid is a literal terrorist is (IMHO) naive.
Both Israel and the Palestinians are between a rock and a hard place, but the only way forward is to get rid of the terrorists who are not playing by any rules - their only wish is for the abolishment of Israel and its non-muslim citizens, with no regards for actual Palestinian lives.
