A hereditary one-party dictatorship of about 26 million people, nuclear-armed and closer to Russia than at any time in decades.
See it on the Geopolitics map →The picture
GDP roughly $25–30 billion (South Korea's central-bank estimate). Ruled by the Kim family and the Workers' Party since 1948; Kim Jong-un since 2011. Strengths: an estimated 50 nuclear warheads, ICBMs, an army of about 1.2 million and artillery within range of Seoul. Weaknesses: poverty, chronic food shortages, UN sanctions, isolation. Allies: China (1961 treaty) and Russia (2024 treaty); rivals: South Korea, the US, Japan. A March 2026 constitutional revision dropped reunification. Investing: none; sanctions bar it.
Why it matters
Its missiles can likely reach the US, and its troops and shells for Russia now tie Korean security to the war in Ukraine.
Key facts and numbers
Bank of Korea estimates, SIPRI warhead counts, UN sanctions-panel reports (until 2024), satellite imagery and state media (KCNA). As of 2026.
What to watch
How many warheads it truly has, whether its ICBM warheads survive reentry, and whether it will conduct a seventh nuclear test, expected by US and South Korean officials since 2022.

▸North Korean troops fight for Russia were sent by North Korea (DPRK)Fact
The relationship
Kim Jong-un sent the troops under the 2024 defense treaty with Russia, the North's first large combat deployment abroad in decades. In return Pyongyang reportedly gains cash, oil, food and possibly military technology, plus combat experience in drone-era warfare.
Since when and why
First units reached Russia's Kursk region in October 2024; North Korea admitted the deployment in April 2025 and later held ceremonies honoring its dead.
How we know
South Korean and Ukrainian intelligence, captured North Korean soldiers, and confirmations by Russia's General Staff and North Korea's state media (KCNA).
What to watch
Exact troop numbers and losses, and what technology Russia has transferred in return.
▸North Korea (DPRK) signed a mutual-defense treaty with RussiaFact
The relationship
Kim and Putin signed the Treaty on Comprehensive Strategic Partnership, whose Article 4 pledges immediate military aid if either is attacked, reviving a Cold War-style alliance. It legitimized North Korean arms and troop shipments to Russia and gave Pyongyang a second great-power protector besides China.
Since when and why
Signed in Pyongyang on June 19, 2024, during Putin's first visit in 24 years; in force from December 4, 2024.
How we know
The treaty text published by both governments; Moscow and Pyongyang later cited Article 4 to justify the Kursk deployment.
What to watch
Whether Russia would really fight for North Korea in a Korean war, and whether the alliance outlasts the Ukraine war.
▸Kim Jong-un rules North Korea (DPRK)Fact
The relationship
Kim rules as general secretary of the Workers' Party, president of State Affairs and supreme military commander, with near-total power. His regime controls information, travel and work, runs political prison camps, and channels scarce resources into nuclear weapons and missiles.
Since when and why
Since his father's death on December 17, 2011; re-elected party chief at the Ninth Party Congress in February 2026.
How we know
State media, defector testimony, satellite imagery of prison camps, and the 2014 UN Commission of Inquiry report.
What to watch
How stable the system is beneath the surface, and how succession would work if he died suddenly.
▸North Korea (DPRK) keeps expanding Nuclear weapons and proliferationFact
The relationship
North Korea left the NPT in 2003 and tested nuclear devices six times from 2006 to 2017. It has an estimated 50 warheads and material for more, ICBMs such as the Hwasong-19, and a 2022 law allowing preemptive use. It calls its nuclear status irreversible and enriches uranium at more than one site.
Since when and why
Tests at Punggye-ri from 2006 to 2017; the Yongbyon reactor and enrichment plants; the Hwasong-19 ICBM test in October 2024.
How we know
Seismic data from the tests, satellite imagery of Yongbyon, state-media photos of Kim at an enrichment hall in 2024, and SIPRI estimates.
What to watch
Whether Russia now shares missile or submarine technology in return for troops, and whether a seventh nuclear test, long prepared at Punggye-ri, is coming.
▸North Korea (DPRK) depends economically on China (People's Republic of China)Fact
The relationship
China accounts for over 90% of North Korea's recorded trade and supplies oil, food and fertilizer, making it the regime's economic lifeline. Beijing values stability and a buffer against US forces above denuclearization, so it enforces UN sanctions loosely. Russia's new support has given Pyongyang more room to maneuver.
Since when and why
The 1961 mutual-aid treaty is China's only formal alliance; Kim stood with Xi and Putin at Beijing's September 2025 military parade.
How we know
Chinese customs data, South Korea's KOTRA trade reports, and former UN sanctions-panel reports documenting smuggling and ship-to-ship transfers.
What to watch
How much Russia now substitutes for China, and how much leverage Beijing really has over Kim's nuclear program.
▸North Korea (DPRK) withdrew in 2003 from Nuclear Non-Proliferation Treaty (NPT)Fact
The relationship
North Korea joined the NPT in 1985, threatened to leave in 1993, then announced its withdrawal in January 2003 after the US accused it of secret uranium enrichment. Free of treaty inspections, it tested its first nuclear device in 2006 and five more by 2017.
Since when and why
Joined December 1985; withdrawal announced January 10, 2003; tests in 2006, 2009, 2013, 2016 (twice) and 2017.
How we know
IAEA records, UN Security Council resolutions after each test, and seismic readings from the test site.
What to watch
Disputed: some states question whether the withdrawal was legally valid; North Korea is the only state ever to leave the treaty.
