Read this post of the perspective of an Israeli on international terror.
The problem is that the civilized world is still having illusions about the rule of law in a totally lawless environment. It is trying to play ice hockey by sending a ballerina ice-skater into the rink or to knock out a heavyweight boxer by a chess player. In the same way that no country has a law against cannibals eating its prime minister, because such an act is unthinkable, international law does not address killers shooting from hospitals, mosques and ambulances, while being protected by their Government or society. International law does not know how to handle someone who sends children to throw stones, stands behind them and shoots with immunity and cannot be arrested because he is sheltered by a Government. International law does not know how to deal with a leader of murderers who is royally and comfortably hosted by a country, which pretends to condemn his acts or just claims to be too weak to arrest him. The amazing thing is that all of these crooks demand protection under international law and define all those who attack them as war criminals, with some Western media repeating the allegations. The good news is that all of this is temporary, because the evolution of international law has always adapted itself to reality. The punishment for suicide murder should be death or arrest before the murder, not during and not after. After every world war, the rules of international law have changed and the same will happen after the present one. But during the twilight zone, a lot of harm can be done.
