Many Germans said that in 1933. I know because I interviewed my grandparents before they died, and they told me so. They fled to Palestine, but many of their friends stayed behind saying, "It can't possibly get that bad." None of their friends survived.
I find it terrifying this gets down voted. We should always keep in mind what the parent said no matter who is running this or any other country. Things like that have happened several times before in history in different scales and we need to remain vigilant to prevent something like it from happening again.
