The 'relocation' wasn't based on anything the Jews had that the Nazis wanted though, not in terms of physical land anyway. Wealth, sure, but the Nazis weren't going after Jews because they had money. The Slavs were gone after for land, definitely, because the Nazis wanted all the land to the east and were happy to just murder anyone and everyone living on it, but even that was based on genetics because the Nazis believed the Slavs to be an inferior species.
Again, what Israel is doing is definitely genocide, there's no arguments there, but it's not the same as the Holocaust. There's a reason the Holocaust is seen as more evil than the Holodomor, and it's because of the sheer industrial evil of it all. A systematic extermination of a people based purely on genetics has some extra weight to it.
