For example, North Korea signed the 1991 Agreement on Reconciliation, Non-Aggression, and Exchanges and Cooperation with South Korea aiming to protect itself from any US-South Korea attempts to march north as the communist bloc was collapsing at the end of the Cold War.
North Korea also signed the 1994 Agreed Framework with the Bill Clinton administration after Washington deliberated striking North Korea’s fledgling nuclear facility.
Pyongyang participated in the Six-Party Talks between 2003 and 2009 as a means to alleviate the US threat after the George W. Bush administration invaded Iraq.
Pyongyang signed the 2012 Leap Day Deal with the Barack Obama administration after the United States overthrew its close friend Libyan Muammar Gaddafi’s regime the year prior.
Donald Trump’s threat of “fire and fury” in 2017 nudged Kim to participate in bilateral summits with South Korean President Moon Jae-in and Trump to obtain a security guarantee for North Korea.
North Korea’s weaknesses meant it had to exploit all windows of opportunity to strike a nuclear deal with Washington and Seoul to lessen the repercussions of the return of hostile figures in either the White House or the Blue House. The mere gesture of talking or sticking to a flimsy deal is enough to dissuade Washington and Seoul from launching a first strike and they buy North Korea time to develop a nuclear deterrent.
North Korea still fears a US-South Korea attack. But its alliance with Russia offers some relief. Pyongyang has committed to its end of the treaty by sending soldiers to defend Russia from Ukrainian counteroffensives. Russia is expected in turn to defend North Korea. Pyongyang’s nuclear program is no obstacle to Moscow’s guarantee, unlike with China, as Beijing doesn’t support North Korea’s nuclear program even while affirming its security guarantee to Pyongyang.
Being able to develop its nuclear program without fear explains why North Korea has not rushed to respond to Lee’s outreach and even asked Trump to recognise it as a nuclear state. Neither Trump’s attacks against North Korea’s close friend Iran nor the use of force to capture Venezuelan President Nicolás Maduro are unlikely to change North Korea’s conditions for talks with Washington. Pyongyang doesn’t seek confrontation with Trump, but it sees little need to actively participate in talks with the United States in search of a security guarantee.
With Russia’s backing and its nuclear weapons growing in terms of quantity and quality, it matters little to North Korea who is in charge at the White House or the Blue House so long as its ties with Russia remain robust. Future US and South Korean presidents, conservative and liberal alike, will have to live with the fact that attacking North Korea is not feasible and an arms control deal is the most cost-effective solution to halt its nuclear program. North Korea has not shunned diplomacy for good. It is just biding time.
