I don't know, some of the prophecies are pretty scary (such as Milchemet Gog uMagog, the "birthpangs of Messiah," and the last pre-Messianic generation having the characteristics of a dog). At any rate, sweetness always seems to be in short supply and horrors are always readily available. How long can the world go on this way? I know: stupid question. It's always gone on regardless of circumstances.
The Talmud records “Some of the descendants of Haman [who in turn was a descendant of Amalek, converted to Judaism and] studied the Torah in public,” and even names R. Shmuel bar Shilas. No one is without hope.
Yes, even I have heard the teaching about Haman's descendants. It does give hope.

...I queried a Chabad Mashpia this past week before I wrote the previous article commented upon. My question was, “Please clarify for me, did the Rebbe say that the Geulah _can_ come without all the negative prophecies of the Nach (biblical prophets) or _will_ come without all the negative prophecies?” He answered, “The Rebbe said the Geulah _CAN_ come without all the negative prophecies.” And I’ll add the Rebbe clearly defined that SOME of the prophecies have already been fulfilled...

...The Melitzer Rebbe, my esteemed and beloved teacher and spiritual guide, explained to me yesterday - in the exact words that he heard from the holy Rebbe Aaron of Belz of blessed memory - that the murder of 6,000,000 Jewish martyrs in the Nazi Holocaust was the pinnacle of Gog and Magog’s attack against Am Yisroel, the people of Israel. As a result, a third of the Jewish people was destroyed.
Gog and Magog are dead...
