The 7 heads are the 7 ideologies which have persecuted God's people: (1) paganism, (2) pseudo-Judaism, (3) Zoroastrianism, (4) Islam, (5) pseudo-Christianity, (6) Communism, and (7) Nazism. Communism seemed "as it were wounded to death" by the fall of the the Berlin Wall in 1989 and the collapse of the Soviet Union shortly thereafter. However, like some monster in a B movie, it is making a resurrenge, all according to what has been prophesied in the Scriptures. See
