There should be a law in Israel that requires Arabs in Israel to say "I swear by Allah that it is wrong to kill Non-Muslims.". Anyone that does not do this should be considered a terrorist. Therefore, the real Muslims that believe in the Koran's command to murder all Non-Muslims should be deported to their own countries. If they have blood on their hand, they should be arrested and charged with the crime they committed. But I don't know if taqiyya allows them to swear falsely, so it might not work. In Judaism, it is absolutely forbidden to swear falsely using the Name of G-d.
