EXPERT OPINION — South Korea’s Korea Institute for Defense Analysis recently publicly stated that we underestimated North Korea’s nuclear weapons program. According to their analysis, North Korea has between 127 and 150 nuclear weapons (not 50 to 60 nuclear weapons), and by 2030 they will have 200 nuclear weapons, reaching 400 nuclear weapons by 2040.

At the eighth Central Committee of the Workers’ Congress in late 2022, North Korean leader Kim Jong Un ordered the exponential expansion of North Korea's nuclear arsenal and the development of a more powerful intercontinental ballistic missile. Mr. Kim reportedly said: “They are now keen on isolating and stifling North Korea…and the prevailing situation calls for redoubled efforts to overwhelmingly beef up our military muscle.”

During this six-day meeting of the Central Committee, Mr. Kim not only called for an “exponential increase in North Korea’s nuclear arsenal”, but he also called for the mass production of battlefield tactical nuclear weapons targeting South Korea, and a new ICBM with a “quick nuclear counterstrike capability; a weapon that could strike the mainland U.S.”

North Korean leaders usually say what they plan to do. Indeed, this is the case with Mr. Kim. Not only has he apparently done this with his arsenal of nuclear weapons, but in October 2025, at the parade celebrating the 80th anniversary of the Korean Workers’ Party, the Hwasong-20, a solid fuel, mobile three stage ICBM capable of targeting the whole of the U.S., was introduced to the international community. The Hwasong-20 possibly could also be capable of launching multiple nuclear warheads at different targets, a capability that would challenge any missile defense system. So, the arsenal of ICBMs that could strike the U.S. – Hwasong-18 and 19 – has also grown exponentially with the Hwasong-20, as Mr. Kim said in 2022.

North Korea has also been working on its submarine program, to include a nuclear-powered submarine. This is in addition to its extensive work on hypersonic and cruise missiles, all representing a challenge to any missile defense system.

North Korea is also developing a second-strike capability, with programs to ensure the survivability of some of North Korea’s nuclear weapons and the progress North Korea has made with solid-fuel mobile ICBMs and nuclear-armed submarines, providing a mobile launch platform. Moreover, North Korea’s doctrine for the use of nuclear weapons has changed to a preemptive, first use of nuclear weapons if a nuclear attack against the leadership or command and control systems is imminent or perceived to be imminent.

Russian President Vladimir visited Pyongyang in June 2024, when he and Mr. Kim signed a mutual defense treaty, part of a “Strategic Comprehensive Partnership” between Russia and North Korea, ratified in November 2024. Article 4 of the treaty states that should either nation “put in a state of war by an armed invasion, the other will provide military and other assistance with all means in its possession without delay”

In October 2024, NATO claimed North Korean soldiers arrived in Russian Kursk Oblast to join Russian forces in its war of aggression with Ukraine. Additionally, North Korea was providing Russia with artillery shells and ballistic missiles. That assistance to Russia continues.

In return, it’s likely that in addition to energy and food assistance, Russia is providing North Korea with assistance with its satellite and ballistic missile programs and, also, with its nuclear program. Indeed, Russia could help with North Korea’s nuclear-powered submarine program, especially with the design, materials and components for such a technically challenging program.

North Korea’s mutual defense treaty with Russia, and its participation in the war with Ukraine, was a major failing of the U.S. and South Korea. We should have seen movement in this direction and did more to prevent it from happening. Of course, there is irony in Russia now saying North Korea should have nuclear weapons when in the Six Party Talks with North Korea, Russia, with China, Japan, South Korea and the U.S., was in sync arguing that North Korea should not have nuclear weapons.

North Korea’s nuclear and ballistic missile programs are an existential threat to the U.S. and its allies. Our past policy to “contain and deter” North Korea and to be “strategically patient” with North Korea didn’t work. They failed, as evidenced by North Korea’s robust nuclear and ballistic missile programs and their allied relationship with Russia – and China. Indeed, efforts should be made by the leadership in the U.S. and South Korea to get Mr. Kim to reengage, especially with President Donald Trump.

As South Korean President Lee Jae Myung said, North and South Korea are in a “very dangerous situation” where an accidental clash is possible at any time.

Mr. Kim’s recent meetings with Russian President Vladimir Putin and the new mutual defense treaty with the Russian Federation have developed into an alliance of unexpected consequences. The 15,000 North Korean troops assisting Russian forces in the Kursk region and the massive amount of artillery shells, drones and ballistic missiles provided to Russia for its war of aggression in Ukraine was a significant development that surprised many of the pundits who viewed North Korea as a distraction, confined to the Korean Peninsula.

Indeed, Mr. Kim’s presence in Beijing for the 80th anniversary of World War II Victory Day celebrations, standing next to Chinese President Xi Jinping and Mr. Putin was testimony to China’s decision that North Korea cannot be ignored and a close alliance with North Korea is in China’s interest.

And certainly, last Friday’s parade and gala in Pyongyang on the 80th anniversary of the founding of the ruling Korean Workers’ Party was an emboldened Mr. Kim announcing to the world that North Korea has arrived and can not be ignored. In the presence of Chinese Premier Li Qiang, former Russian President Dmitry Medvedev and Vietnam’s Communist Party Chief To Lam and others, Kim made it clear when he said North Korea “was a faithful member of Socialist forces… and a bulwark for independence… against the West’s global hegemony.”

Doubling down, North Korea at the military parade introduced their new Intercontinental Ballistic Missile, the Hwasong-20, a solid fuel massive missile capable of carrying multiple nuclear warheads and capable of targeting the whole of the U.S. Other weaponry, to include hypersonic and cruise missiles also were on display, making it clear that Mr. Kim was serious when he said North Korea would enhance its nuclear capabilities.

At a recent Workers’ Party Plenary session, Mr. Kim said he was prepared to meet with Mr. Trump, on the condition that the U.S. would accept North Korea as a nuclear weapons state. Mr. Kim spoke of fond memories of his previous encounters with Mr. Trump. And at the United Nations on September 29, after seven years of no-show, North Korea’s Vice Foreign Minister Kim Son-Gyong said North Korea would never give-up its nuclear weapons; to do so would be tantamount to giving up its sovereignty.

Indeed, North Korea succeeded in getting Russia to accept its nuclear weapons status. Russia was a member of the Six Party Talks with North Korea and actively assisted the U.S., South Korea, Japan and China in demanding that North Korea denuclearize completely and verifiably. Russia is now saying North Korea should retain and enhance its nuclear weapons and is probably assisting North Korea with its nuclear weapons program.

Hopefully, China will not relent and continue to demand that North Korea denuclearize. Some say that China is now less committed to North Korean denuclearization than in the past. It’s likely this was discussed when North Korea’s Foreign Minister, Choe Son Hui, met with her counterpart in China, Foreign Minister Wang Yi. Interestingly, both participated in the Six Party Talks with North Korea, when Mr. Wang was the chairman of the Talks in Beijing and Ms. Choe was an adviser to Vice Foreign Minister Kim Kye Kwan, head of the North Korean delegation to the Talks.

North Korea’s goal is to have a normal relationship with the U.S. This is something Mr. Kim’s father, Kim Jong il, and grandfather, Kim il Sung, pursued since 1994. A relationship with the U.S. would give North Korea international credibility and access to international financial institutions for economic development purposes. It will also untether North Korea to China. It is no secret that historically, and even after Mr. Xi assumed power in China in 2013, the bilateral relationship between North Korea and China has been tense.

And indeed, given North Korea’s experience in dealing with the former Soviet Union in 1991, at the end of the Cold War, when Moscow downgraded relations with North Korea and in 1995, when Russia officially renounced the mutual assistance treaty with North Korea. It, therefore, should be obvious to North Korea that once the war in Ukraine is over, Russia’s need for continued North Korean assistance will end and the relationship will likely be downgraded.

This is the time for Mr. Trump to meet with Mr. Kim to talk about security assurances and a path to normal bilateral relations. The issue of North Korea’s nuclear status need not be the focal point for future discussions. It should, however, continue to be our goal, but at an appropriate time.

I’m not surprised by Mr. Kim’s comments. When the Six Party Talks with North Korea commenced in 2003, North Korea’s principal representative to the Talks often mentioned that North Korea wanted nuclear weapons as a deterrent, never to be used for offensive purposes. They asked to be treated as we treated Pakistan, a country that has good relations with the U.S. The North Korean representative said North Korea wanted a good, normal relationship with the U.S., promising to be a good partner. with the U.S.

North Korea has consistently been told that the U.S. would never accept North Korea as a nuclear weapons state. But with complete and verifiable denuclearization, North Korea would receive security assurances, sanctions relief, economic development assistance, to include the provision of Light Water Reactors for civilian purposes and eventual normalization of relations with the U.S. Mr. Kim’s father, Kim Jong il, seemingly accepted this U.S. offer and in September 2005, North Korea did agree to a Joint Statement committing North Korea to complete and verifiable denuclearization of the Korean Peninsula.

That was 2005. The situation has changed profoundly over the past twenty years. North Korea now has a formidable arsenal of nuclear weapons; some estimates are between 50 and 60 nuclear warheads, reportedly with sufficient fissile material to annually produce 15 to 20 nuclear warheads that can be miniaturized and mated to ballistic missiles.

North Korea’s sixth nuclear test in 2017 was assessed to be a test of a thermonuclear weapon. And in 2024, North Korea successfully launched the Hwasong/19, a mobile, solid fuel ballistic missile capable of targeting the whole of the U.S. In addition to advances in nuclear weaponization and ballistic missiles, North Korea has made significant progress with Hypersonic and cruise missiles and advances with its nuclear submarine program.

Of note is North Korea’s new mutual defense treaty with the Russian Federation and the 12,000 combat troops North Korea sent to Russia for its war with Ukraine. In addition to the troops, North Korea has provided Russia with large quantities of artillery shells and ballistic missiles. In exchange, Russia has provided North Korea with considerable technical support for its satellite and nuclear and ballistic missile programs.

We are now dealing with a different North Korea. Mr. Kim is more self-confident, given his new relationship with Russia and his continued close allied relationship with China. Having two of the five permanent members of the United Nations Security Council ensures that North Korea no longer must be concerned with UN sanctions. And the pictures of Mr. Kim at the parade marking the 80th anniversary of the end of World War Two in Beijing, standing next to China’s Xi Jinping and Russia’s Vladimir Putin, gave Mr. Kim significant international credibility, especially with the Global South.

A meeting of President Trump with Chairman Kim could develop into a series of meetings that could result in North Korea halting the further production of fissile material for nuclear weapons, with no additional nuclear tests and a moratorium on ballistic missile launches. This would be a major success for Mr. Trump and the U.S. It would also lessen tension with South Korea and Japan.

The “eventual” U.S. goal should continue to be complete and verifiable denuclearization. However, this doesn’t have to be up front. It’s an eventual goal that should be pursued as relations with North Korea improve, with an action-for action process: As North Korea halts the production of fissile material and stops producing more nuclear weapons and refrains from ballistic missile launches, UN sanctions imposed subsequent to 2016 could be lifted with security assurances and economic development assistance and a discussion of liaison offices in our respective capitals. North Korea should be encouraged to rejoin the Treaty on the Non-Proliferation of nuclear weapons (NPT).

Mr. Trump entering talks with Mr. Kim could develop into a relationship with North Korea that could prove beneficial for the U.S. and its allies and partners.
