Both sides also pledged to cooperate to recover the remains of those soldiers still counted as “prisoners of war” (POWs) or “missing in action” (MIA). While a new relationship is hard to come by, the POW/MIA issue is one that the two enemies can quickly cooperate on at a low cost and build confidence towards normalisation. In contrast to its foot-dragging in denuclearisation negotiations, North Korea sent back 55 US war remains one month after the 2018 Singapore summit. Moon also explained in his speech in September that the search for the remains of POWs/MIAs could contribute to building peace on the Korean peninsula.
Is there truly a prospect for a more normal US-North Korea relationship? Could further cooperation on POW/MIA issues break the current deadlock in denuclearisation talks and declaring the end to the Korean war?
The experience following the Vietnam war provides some basis for comparison. The POW/MIA issue was a major area of cooperation before Hanoi and Washington finally normalised relations in 1995. Understanding how the US-Vietnam negotiations progressed helps shed light on the US priority between security interests and reconciling with a former enemy.
The United States and Vietnam began serious MIA talks in the mid-1980s, when Hanoi was still occupying Cambodia and US-Vietnam relations were adversarial. The United States and Vietnam had attempted to normalise relations in 1977, but Vietnam’s invasion of Cambodia in 1978 put an end to the efforts. As both sides reconnected to discuss MIA issues, the United States made clear that MIA talks would not mean it was normalising relations with Hanoi, and it would not do so while Vietnamese troops remained in Cambodia.
Many American officials were sceptical of Vietnamese intentions in these MIA talks, thinking that Hanoi was using the war dead as a leverage to get US diplomatic recognition despite its military presence in Cambodia. However, US-Vietnam relations quickly improved in 1990 as Hanoi had fully withdrawn troops from Cambodia a year prior. The United States still did not lift a trade embargo on Vietnam, pending a political settlement for Cambodia.
Only after the 1991 Cambodian Peace Agreement was signed did the United States signal it was open to talking normalisation with Hanoi. In the years after, despite slow progress on the MIA issue, the Clinton administration decided to lift an embargo early on the grounds that a better relationship would help, not hinder, the search for MIA soldiers. Moreover, better US-Vietnam ties would help check the rise of China.
The US-Vietnam normalisation process shows that Washington can prioritise its security interests above the POW/MIA issue, looking for its counterpart to make concrete commitments before ending the state of enmity.
