Someone tried to wipe out the Jews, so nationalism for a Jewish state must be healthy too, right?

Or maybe nationalism is just a tool to manipulate people and make them ignorant of the problems in a government. Fatah is incredibly corrupt but you don’t seem to care about that because you believe in some nationalistic narrative. There would already be a Palestinian state if there was strong leadership. But using narratives about historical humiliation, misogyny, hatred of other ethnic groups, reclaiming a glorious past (all hallmarks of fascist manipulation) means people are less likely to demand better leadership and corrupt governments can persist.
