You had better pray That he doesn't have Nukes. It's not even a Joking manner. It won't just be thousands killed. It will be Millions, upon millions, upon millions.
But something I find strange, If they shoot the nukes at us, doesn't it seem that we could track something like that moving by sub radar or even satellite technology? And since we know exactly where it is couldn't we just target a few Icbm's a blast it down before it hits mainland?
