They think ”they” can bring about their Messiah by the way of terrible violence and worldwide destruction. They think they can bring about his return. Not that one day he will just show up but that they can “make it happen” Many do not go along with this but many of the Leaders of these countries do. The few that do not believe will not be able to stop their plan.
Even if “you” not believe this “they do” and that makes them dangerous.
