The United States and South Korea issued a joint statement saying that the United States is to place a THAAD (Terminal High-Altitude Area Defense) anti-missile system in South Korea. The system uses radar to identify approaching missiles, against which interceptor missiles can be fired. It would be under control of the United States military. According to the statement, the system

will be focused solely on North Korean nuclear and missile threats and would not be directed towards any third party nations.

The Chinese Foreign Ministry said that it "expresses strong dissatisfaction and firm opposition" and called for a "stop" to the deployment.

    Though this is true for conventional missiles any nuclear missiles need to be detonated quite a bit above the ground in order to cause the most devastation.

    If the nuke is launched upwards from the edge of the DMZ, and explodes on the upward trajectory (likely killing the people who launched it) none of the missile defense systems will work because they all rely on the missile becoming "ballistic" as in no longer operating under its own power but instead being pulled by gravity. When a missile is ballistic its trajectory becomes predictable.

    Not really, while it is true that an air burst will maximize the destructive radius of a blast even a ground burst will completely destroy Seoul.

    Back during the cold war one of the biggest concerns the Americans had was a little trick known as a "depressed trajectory" ICBM launch. Instead of having the missile accelerate up then have the warhead free fall back down in a normal ballistic trajectory, which is where THADD would be effective, you have the missile go sideways from the launch point and make a shallow arch to the target. The missile would be in it's acceleration phase most of the way and could even detonate before it finished its primary burn. The THADD system is useless against that kind of launch.

    What gave the DoJ nightmares was having a Soviet "Boomer" sneak up on the coast line and execute DT launches at critical targets. According to the simulations they had a good chance of getting many high value targets before an alert could even be sounded. It was one of the reasons the US had flight ready bombers on the runway 24/7 with engine running and ready to lift the instant there was an alert. Those and the subs were the primary things that guaranteed the MAD policy kept anyone from trying to get in a first strike.

    There would be no winners, so no one wanted to risk playing

      And yet in 9/11 the military officially got zero of the planes.

        That is because

        A: the military happened to be conducting "training exercises" that month involving simulated high jacked planes so there was initial confusion in the FAA about whether the 4 planes had actually had been high jacked. By the time they figured it out it was too late.

        B: the fighter jets that could have intercepted the high jacked plans had been sent hundreds of miles away from where the planes that had really been high jacked making a timely intercept impossible. The exact reasons didn't get explained in the official report.

        Lots of other interesting things happening around and before the morning of September 11th, 2001. Most can be written off as just coincidence and back luck but some of it can really make you wonder if you bother to look into it.

      Why did they care? Not their job.

      DoJ? Or do you mean the DoD?
