Here are some solutions.

1. Bomb the shit out of the mansions of the HAMAS leadership in Gaza. Let the UN explain the broken swimming pools, and the fat Swiss bank accounts.

2. Without apology set up a tracking array that calculates the trajectories and origins of a mortar or rocket. The second a rocket or mortar is detected, automated artillery will open a barrage. Announce the system is automated and designed to take out a .5 mile radius. Announce that any civilians killed in the barrgae were killed by the actions of the terrorists since the system is automated.

3. Do not flinch when they launch from a school. Say calmly that Hamas killed those people. Do this enough and people will not want rockets launched near them.
