Here's a solution:
Whenever an Arab is hit with a rock by another Arab, or whenever they need free medical attention that they leach off the "cruel, oppressive Jews, and the 'apartheid' Israeli Government occpupation forces", they should be forced to sign a paper saying that they will leave Israel.
If they (or their parents) don't sign, no treatment.
If they sign, we can treat them and as soon as they get out of the hospitable bed, they gather their belongings and are on a train out of Israel and not allowed anywhere within the boarders of Eretz Israel.
They get to leave with their lives and plenty of Arab nations for them to settle in.
Else they can try their luck in the Gaza local hospital.
