Sure. It's further of a stretch of the imagination to think Korean birds can really fly across the Pacific Ocean.
No, because they cannot reach us. It is for peace of mind. That and North Korea has such low grade technology all we really need are 10. Edit @Steven m. They do not have nuclear submarines and they certainly do not have submarines capable of launching missiles. Neither does Iran. And even if they did they would be so loud our sonar operators would go deaf tracking them.
North Korea has yet to put a satellite in Orbit which is a general indication of developing technolhy capable of ICBMs other delivery systems are available of course they could take over a KAL 747 enroute to JFK for a suicide mission for example
certainly not from a Korean Nuclear Submarine a few miles off Washington or New York During the Cold War we were told a Sub launched Missile, would have a warning of less than two minutes Technology has improved in the twenty or thirty years since this statement The creation of Stealth missiles could mean no warning A new weapons race is the last thing our Planet needs at the moment Problem is new countries are trying to find their place in the pecking order, Sabre Rattling is one of the oldest ways of getting attention Maybe the USA instead should offer them a Trade deal
Just how many missiles do you think the North Koreans have? They manage to test one about every three years. If the North Koreans actually launch against the USA that nation will cease to exist 15 to 20 minutes before Little Kim has a chance to see the results of his missile.
