My point, obviously, was that it isn’t necessarily a good thing. In a certain sense the holocaust and the medina are a good thing; we’ll find out how these bad things are really good when Moshiach comes.
As far as Ma’ase Satan, a Ma’ase Satan is also Retzon HaBorei. So both the holocaust and the medina are Ma’ase Satan that is the Retzon HaBorei.
