Trying to provoke Armageddon is dangerous whether you want to think so or not.
The whole idea of hastening a huge war so that Jesus will come sooner is dangerous. This isn't a bunch of people who are standing on a hill waiting for the sky to open up. This is a potent group of political activists who have the ear of the head of the most powerful nation on Earth. In their minds, it doesn't matter what happens to the world because they are already saved.
