In North Korea, North Korea is one of the most militarized countries in the World, and the Korean People's Army (KPA) is one of the World’s largest military forces; founded in 1948, the KPA’s primary responsibilities are national defense and protection of the Kim regime; it also provides considerable support to domestic economic projects such as agriculture production and infrastructure construction; North Korea views the US as its primary external security threat 

in addition to the invasion of South Korea and the subsequent Korean War (1950-53), North Korea from the 1960s to the 1980s launched a considerable number of limited military and subversive actions against South Korea using special forces and terrorist tactics; including aggressive skirmishes along the DMZ, overt attempts to assassinate South Korean leaders, kidnappings, the bombing of an airliner, and a failed effort in 1968 to foment an insurrection and conduct a guerrilla war in the South with more than 100 seaborne commandos; from the 1990s until 2010, the North lost two submarines and a semi-submersible boat attempting to insert infiltrators into the South (1996, 1998) and provoked several engagements in the Northwest Islands area along the disputed Northern Limit Line (NLL), including naval skirmishes between patrol boats in 1999 and 2002, the torpedoing and sinking of a South Korean Navy corvette in 2010, and the bombardment of a South Korean military installation on Yeonpyeong Island, also in 2010; since 2010, further minor incidents continue to occur periodically along the DMZ, where both the KPA and the South Korean military maintain large numbers of troops; in late 2023 and early 2024, the Kim regime abandoned decades of official policy and declared that South Korea was not inhabited by “fellow countrymen” but a separate and “hostile” state that the North would “subjugate” if war broke out

North Korea also has a history of provocative regional military actions and posturing that are of major concern to the international community, including: proliferation of military-related items; ballistic and cruise missile development and testing; weapons of mass destruction (WMD) programs including tests of nuclear devices in 2006, 2009, 2013, 2016, and 2017; and large conventional armed forces; despite high-level efforts to ease tensions during the 2018-19 timeframe, including summits with the leaders of China, South Korea, and the US, North Korea has continued developing its WMD programs and, in recent years, issued statements condemning the US and vowing to further strengthen its military capabilities, including long range missiles and nuclear weapons (2024)
