It's actually a common misunderstanding even on an individual level. For some reason there's this popular idea that if someone has suffered, that they'll come out of it more enlightened and compassionate.

Like NO. That isn't how psychology works. Trauma doesn't magically make you a better person, any more than comfort and privilege does. Hurt people hurt people, as the saying goes. Not always, but often enough.

Hell in Israels' case most of them haven't even suffered in any camps, their grandparents did. They just like to use it as a collective civilizational pass and excuse to be allowed to do whatever they want. Israel has even turned on the nations that support it whenever it suits them, such as when they stole nuclear secrets and material from the west for their (illegal) nuke program.

Also it's worth noting that a good chunk of Israels' support has nothing to do with what Nazi Germany did to the Jews. A lot of its official govt. support from the US is just cold geopolitics, using Israel as a forward base in the ME. But besides that, even on an individual level, say, the Rapture fanaticists among American evangelicals don't care what the Nazis did - they support Israel no matter what it does simply to fulfil their dumb End Times prophecy.
