Cultural and religious belief that the land belongs to them by divine right, and was stolen. WWII enabled them to resettle in their "home", but the principle of ownership didn't come out of WWII. The treatment of the Jewish people in WWII doesn't mitigate these beliefs, and may even strengthen them (ie, persistence and survival are further evidence of divine right)

(These aren't necessarily my opinions, and I am not Jewish. However I'm very closely connected to people who are, and I'm sharing the perspective I've been given)
