According to the Bible, the Israelites took possession of the land of Israel through a brutal campaign of genocide. Why has the state of Israel not been charged by the International Criminal Court for these crimes against humanity?

Oh, probably because if you play that game every group of people took possession of the land through a brutal campaign of violence or genocide, and there would be no end to it. Where does it all end? The Fertile Crescent, and Persians get everything?

Furthermore, when a person is dead, they are not dug up and put on trial. Likewise groups of people are not responsible for the trespasses of those who came before them. Certainly civil cases have been brought by descendants to retrive what was taken from them, like artwork Nazis took, but as far as land, eh. If Native Americans sue the United States, then tribes that displaced other tribes could do the same, and only those who have DNA of the people who first to inhabited North America would be the final winners. The Middle East is an even worse, and a more confusing scenario, and it is not even a doable thing, even if it was a correct thing to do, which it is not. It is nothing more than a purely political ploy, once again, against the Jews. Doesn't this crap ever get old?

Israel has never been the problem. The problem is, anytime Israel gets attacked it kicks the ass of those who attacked it, and takes land off of them (typically that land has been given back. Boo Hiss!) And that problem is not one I have any sympathy for the agressors and losers of those conflicts. So sad, too bad. Go ahead, attack Israel again, and I hope they keep the land they take, and populate it with plenty of Jews, and build Temples on top of what were once Mosques. At this point, that would be justice.
