I've seen these war criminals many times, if warrants are issued they will be acted upon sooner or later. I can see this monster being arrested and handed over to the new Israeli authorities, when he's 95, that's about 20 years away. By that time Zionist Israel will have collapsed, its racist regime destroyed and the nation will have moved forward. No more walls, no more illegal settlements and so on, Netanyahu will just be an embarrassment, the people of Israel will want closure.
At that time few will remember him, he will have been out of the public eye for so many years he is all but forgotten but the long arm of the law will prevail and like the Nazi criminals before him, he will be hunted down, nobody will protect him, he'll have few friends, he'll be toxic. He'll then be made to pay for his genocide and mass murder and deaths of Israeli hostages, perhaps even be hanged as the Nazis were.
