Considering how fond USA has become of the nazis recently (again), I think you're wrong. It's absolutely important to get history consistently hammered into your skull, or some dipshit is going to abuse the ignorance of the people.
And to add, it's not like it's really that distant history. My grandfather fled the nazis when his brothers were sent to a work camp.
