So far, they’ve been unable to launch one, but experts are saying that the US can’t shoot them down. There have been successful missile defense systems, such as the Patriots and Iron Dome. But even so, we can’t get them all, the experts say. One thing is certain, if they use nuclear weapons on the US and one of them hit, the Norks won’t be able to stop any of the US’ ICBMs.
And IF nork has any of those capabilities, I'm guessing it's one and done. They might manage to deliver one, which would exhaust not only their supply but our -- and the world's -- patience. They'd be signing their own death warrant.
