The main enemy "Korea" that General Kim refers to here is essentially a pan-geographical concept, which means all enemies in this land; For example, in addition to the South Korean army, which is nominally a direct enemy, it also includes the US military stationed in South Korea and Japan, and even the Japanese army that may intervene in a war in the future. The "Songun politics" implemented by the whole country of North Korea is mainly aimed at not the South Korean ** team, but the US military, and even the US mainland on the other side of the Pacific Ocean; In fact, the DPRK has been preparing in this direction for so many years. 
However, the DPRK's economy is really not good, and even now it has to rely on imports of grain and relief from other countries, especially the DPRK's industrial capacity is not strong. In 2022, North Korea's steel output will be about 700,000 tons, equivalent to one-third of Belarus, one-tenth of Ukraine, one-twentieth of Iran, and one-sixtieth of South Korea, which is still crude steel; Some people even ridiculed that the surface ships of North Korea are not worth as much as several yachts of the Emperor combined. But the DPRK knows that the limited money is used on the knife edge, and with the "mutual support" with Russia in the past two years, the North Korean troops have exploded into huge combat effectiveness in a short period of time. For example, the DPRK's nuclear power has advanced by leaps and bounds in a short period of time, and it has successfully conducted three nuclear tests in succession, and its yield has become larger and larger, and even plutonium has been realized. After General Kim and Putin met for the first time in 2019, three improved versions of North Korea's Polaris series of submarine-launched missiles quickly appeared, and hypersonic missiles were developed in less than two years. In 2022, less than a year after North Korea was the first in the world to recognize the independence of the two continents in Ukraine, North Korea's intercontinental missile "Hwasong-18" was successfully tested; The test of the intercontinental ballistic missile "Hwasong-18" was a typical high-trajectory flight test. The height of the apex of the ballistic trajectory reached a staggering 6000 km. The equivalent effective range is about 15,000 to 16,000 kilometers, which is completely capable of hitting the entire territory of the United States, and even hitting London in Europe. 
There is also a spy satellite, after the first two launches failed, after a meeting with Kim Pu at the Dongfang launch site, the DPRK's third spy satellite was successfully launched, and the "Wanlijing-1" has already transmitted image data from many places, including North America. In addition, many people suspect that North Korea's high-profile display of the first nuclear submarine launching scene is fake, but North Korea did not make this kind of thing to coax South Korea to play. The aim is to strengthen North Korea's nuclear submarine capabilities and allow the North Korean military to form a more threatening "three-in-one strategic nuclear strike capability." All this is to greet the ubiquitous US military. So what about South Korea? It's hardly worth mentioning for North Korea. Seoul is less than 40 kilometers from the demarcation line. If the two Koreas do go to war, North Korea will be able to greet South Korea with long-range artillery and super-large-caliber rocket artillery with a certain guidance capability. 
The DPRK army pursues the "artillery doctrine", and artillery is the backbone of the DPRK army. What is little known is that the DPRK is the number one artillery power in the world. The United States once reported that the artillery units of the Korean People's Army are equipped with more than 20,000 artillery pieces, ranking first in the world in terms of total number. North Korea only needs to use artillery units to deliver powerful strikes against almost all important targets in South Korea. Therefore, it is impossible for the DPRK to deal with the ROK with an ICBM with a range of more than 10,000 kilometers at every turn. In addition, the North Korean side has an astonishing stockpile of artillery shells, and although it has been too long for many to become duds, it is no problem to carefully inventory the inventory and find millions of rounds that can sound. The number of shells sold to Russia during this period alone is conservatively estimated at more than a million. So it's easier to deal with South Korea.
