There is a particular religious group that claims to have deciphered and worked out the core message of the Book of Revelations...
They have established that it speaks of climate changes, the rising of Islam against Christianity,and Israelite against Palestinian....
They say that there's little point in attemting to divert these happenings, as they are the 'will of God'. Some even promote these prophesies and actively encourage these things to take place.
A large proportion of this group work in the Pentagon and the White House.
Now, that's scary.
