Medved blew it completely.
The Bible indicates that Satan hates the Jews. Because of that, we've seen one civilization after another attack the Jews, not for anything they have done, but because they exist.
The idea that Jews did something to "deserve" the holocaust, or Britain's betrayal in the 1930s, or Stalin announcing in 1953 of another pogrom (Beriya had apparently had enough of the murder campaigns and poisoned him), and the hundreds of other genocides on record were not because the Jews did anything, good or bad.
It's because they exist.
Islam makes a sacrament of murdering the "people of the book", that is Christians and Jews, because they exist. Not for anything they have done.
If there is an exceptional proof for the existence of satan, it's in the constant attacks on the Hebrews since they started existing.
