Wow, freepers are really helping me out. One thing, though I forget who wrote it, but I don't think any Christian wishes for war, they wish simply for what God intends. So I think it would be wrong to simply say "they want a huge war" so Christ can return," they simply want what they beleive God has laid out.
Christ does not require a 'huge war' to generate his second coming. Wars and rumors of wars, have been the status of mankind since the dawn of recorded history.
Jesus will come when he is good and ready, and not a moment sooner.
