This is my plan of how to restore the light rail to Pisgat Ze'ev.
Build a fence around the light rail in the Arab neighborhood and don't rebuild the stations there. Just restore the infrastructure (rails, wires, traffic signals, etc...). Then fence in the Arabs as if their neighborhood is a zoo so they can't destroy Jewish infrastructure. Even animals in a zoo don't act like this. The lions and tigers don't destroy stuff in their environment and don't attack people unprovoked.
