Simple question, but I suppose there may be lots of opinions for many different reasons! Unlike Obama, when he was debating Romney about the size of the military, I do not have a lot of faith in technology winning wars. I say this because of the EMP's .... that even North Korea may possess!

That may be a literal understanding, but I don't think the prophets got it wrong. I think they saw clearly; that technology and modern warfare technology and machinery would be ineffective in the final battle between good and evil!
