President Trump’s confrontational “Make America Great Again” foreign policy put the United States and its allies on a collision course with each other and with China. It focused far too much diplomatic and public attention on US-China competition and eroded the liberal world order by creating a situation whereby the US itself began questioning its value. It also gave little support to nations and allies interested in finding inclusive solutions to tackle global problems by pitching countries as “for” or “against” major powers. In short, it did little for the advancement of our common interests and generated high levels of mistrust and unpredictability.

With the inauguration of Joe Biden as the next American president all but certain, the eyes of the world are once again turning to the US. People are speculating about the policy line to be adopted by Biden, who has promised to value American alliances and restore multilateralism in the international community in a departure from Donald Trump’s “America First” approach. But little is known about what policy the Biden administration will adopt on the North Korean nuclear issue, the topic of greatest interest to those of us in South Korea.

It is diplomats’ job to re-evaluate alliances to suit our interests, and they shouldn’t be criticised for it. South Korea’s conservative establishment has been harshly critical of the Moon administration’s attitude toward the South Korea-US alliance. The latest controversy concerns recent remarks by Foreign Minister Kang Kyung-wha and Lee Soo-hyuck, South Korean ambassador to the US.

After three years of an erratic approach to North Korea, the Trump administration has made little progress in reducing the nuclear threat and enhancing peace and security on the Korean Peninsula. Today, North Korea continues to enrich uranium, enhance its missile capabilities, and reverse the inter-Korean conciliatory measures taken in 2018. The next US president will have to address this grave situation.
