For decades, US President Donald Trump vowed to rid the world of nuclear weapons. As late as July Trump indicated his desire to maintain the limits set out under New START. But what to make of Trump’s announcement that he will authorise the recommencement of nuclear testing? US Energy Secretary Chris Wright, who maintains the nuclear arsenal, sought to dampen anxious responses by explaining the US was considering “system tests” which involve “non-critical explosions”, not nuclear detonations.
But nuclear experts are on high alert as yet another global norm underpinning the “nuclear taboo”, the Comprehensive Test Ban Treaty, is undermined.
More than two decades after my discussion with the North Korean foreign minister, what are we to make of nuclear ambitions and changing power relativities in our own region?
Paek’s fear back then of US air power illustrated deterrence at its most basic task – a show of power which can change the mindset of an adversary, to prevent or curtail war. Plus, the significance of conventional military “lift” capability in the form of fighter jets, even as we talk nervously about nukes.
Asian partners and allies need to hear the US President say that the nuclear taboo remains cogent as the United States will honour its promise of extended deterrence. Noting that promise does not imply a nuclear strike will be met with a nuclear strike but can and should involve US conventional responses.
Perhaps amid the chaotic White House messaging Trump will revisit his commitment to rid the world of nuclear weapons and use his power and relationships with Putin and Xi – however fraught – to convince them both to reset the global nuclear strategic balance.
Paek’s paranoia – misreading the threat – probably indicated that the Kim regime was moving rapidly towards nuclear weapons, though I did not know that at the time.
But it highlighted a danger even more apparent today, that of potential strategic miscalculation by nuclear-armed adversaries.
