It CAN happen now or in the future, but it's not. Never before in history has the world (outside of Islam) been so supportive of the Jews.
It's not perfect, and there is certainly anti-semitism in the world but you should appreciate how far the world has come. If you expect perfection you will always be disappointed.
I don't know that I would word it like that. The world SHOULDN'T have to come far to treat anyone right.
Now being Jews I do find it amazing how "good" we have it. And make no mistake, we do.
But there is plenty of anti Semitism in the world. Sometimes it's loud and sometimes not. But it's there. And we'd be silly to not be aware of it.
The same way black people have "come so far". Meanwhile there are still plenty of racists walking this earth. And the struggle and hatred is still there.
