It is impossible to believe such a thing, particularly because Jewish Americans would have millions of Christian Americans to protect them. And don't think we wouldn't. And no, we wouldn't insist on conversions, who cares about that?
You misunderstand me; probably I was not clear on this issue. It does not matter which group of populace will get the most abuse.
The scenario, I described, may indeed not happen - America is still a country very different from others, it’s the country where individual rights still mean something.
However, if you take any country in the past where a Dear Leader, with adoring, crazed mob surrounding him, came to power, those countries - all, no exception - suffered (and many still suffer) extreme forms of Government abuse and suppression of the individual freedoms.
