The Palestine comparison doesn't work. Palestinians didn't show up to an abandoned plot of land and lay down stakes and are now being shoved out by a people who decided to come back and reclaim everything, Jews have lived on that land continually for 6,000 years. It would only work if the Dwarves lived in Khazad-Dum the entire time and the goblins just up and decided one day that the goblin god has decreed that all dwarves be killed or removed from the mines. Then it would be a valid comparison.
