It follows that if assassinations of terrorists in 1973 were lawful instances of justice and counterterrorism, the formal arrest of a terrorist mastermind for judicial punishment would certainly be entirely permissible. Only one thing can be predicted with certainty. Whatever is done will be done for considerations of Realpolitik. Whatever is done will be done for political rather than legal reasons. From the standpoint of law, however, it is essential that Daoud be prosecuted, in one jurisdiction or another, for his openly admitted crimes.
Every state has an obligation under international law to seek out and to help prosecute terrorists.
It is codified directly in many different sources, and has origins in the ancient Jewish law of exact retaliation, or Lex Talionis, which is presented in three separate passages of the Torah. No government on earth has the right to pardon or grant immunity from prosecution to terrorists with respect to criminally sanctionable violations of international law. This limitation derives from a broader prohibition that binds all states, including Jordan, Israel and the United States, namely the persistently overriding claims of Higher Law or the Law of Nature. There is one last point - a point specifically about Israel and Jewish justice. Today, Israel offers the murderers of its Jewish citizens a VIP pass.
