The NKs wanted to convince everyone they are dangerous. They succeeded.
Jeremy, it occurs to me that this is a Godsend for the God Emperor. The war mongers of the Deep State will not rest until he embraces the 24-7 war room presidency that Wolf Blitzer named his CNN show after. North Korea could be a place where the war merchants of the intelligence community can get on the same page as a president who only wants to fight against threats to U.S. national security. If I was Trump I'd broker a deal with the CIA goons to stay off my back about Russia if I give the go ahead to hit North Korea. You have a willing ally on the ground, you don't have to declare war, and my brother Bobby is no longer commanding an Abrams on the 38th parallel—so what's not to like?
The White House is considering direct military action to counter North Korea
South Korea is Turning The Tables On North Korea - Strategy Page
South Korea prepares to take the fight to the enemy in the event of war with the North. North Korea still has the largest number of special operations soldiers in the world; however, South Korea is catching up in numbers and now exceeds the North in capability.
“South Korea has since 2015 been adapting its military organization and strategy to deal with the rapidly changing situation in North Korea. For example South Korea has organized six special operations teams that are trained to attack and destroy key targets inside North Korea. This represents a major change in special operations in Korea because since the 1950s it was North Korea that was constantly sending commandos and spies into South Korea where not all of them were quickly caught or caught at all. At the same time until recently it has proved nearly impossible to get foreign agents into North Korea, which had been turned into the ultimate police state since its creation right after World War II. Since the 1990s the lack of Russian aid (which kept North Korea afloat since the 1950s) caused the North Korean military to gradually (and almost imperceptibly) fall apart. This accelerated because of growing economic problems and corruption, even spreading to the secret police and other security agencies. As a result South Korea considers North Korea vulnerable and is preparing to take advantage of that during the next military emergency. If nothing else it compels the North Koreans to spend a lot more on protecting their nuclear weapons. The latest revision of South Korean strategy specifically mentioned plans to go after nuclear weapons, ballistic missiles and key leaders. Much of this will be done with the new strike aircraft (F-15Es) carrying stealthy cruise missiles and smart bombs. South Korea also has obtained more missiles that can hit the North Korean forces concentrated near the border (DMZ or Demilitarized Zone).”
“South Korea has fewer (about 20,000) special operations troops but they are trained and equipped to a higher (Western) standard. Meanwhile South Korea has improved its air defenses along the DMZ. For over half a century North Korea has prepared to fly small single engine transports into South Korea by coming in so low the radar could not pick it up. South Korea can now detect such low flying aircraft and has weapons on the DMZ to quickly shoot down intruders. The pilots of these aircraft are not as skilled as they used to be, especially for low altitude night flying, because fuel shortages have sharply cut training time in the air. “
The single engine aircraft employed by North Korean Special Forces for infiltration is the Antonov An-2 “Colt”. https://en.wikipedia.org/wiki/Antonov_An-2
The Antonov An-2 (Russian nickname: "Annushka" or "Annie"; "kukuruznik" - corn crop duster; USAF/DoD reporting name Type 22, NATO reporting name Colt.) is a Soviet mass-produced single-engine biplane utility/agricultural aircraft designed and manufactured by the Antonov Design Bureau beginning in 1946. Its remarkable durability, high lifting power, and ability to take off and land from poor runways have given it a long service life. The An-2 is still produced and remains in service with military and civilian operators around the world. In certain wind conditions it can hover or even fly backwards.[7
