No one is personally responsible for the deeds of their compatriots or fellow believers, or for governmental policies.
I feel like Netenyahu can be held personally responsible for the actions of his government, though.
If not him, then who? Should the world simply put the palestinian genocide behind them? What if the world had done that with the jewish holocaust?
Consider the Nuremburg trials1, where several prominent Nazis were held personally responsible for the actions of their government. Should that not have happened?
