Experts have widely speculated that Joe Biden, who served eight years as vice president under former President Barack Obama, may return to Obama's "strategic patience" in dealing with North Korea when the two countries did not engage in diplomacy.

One of the biggest concerns about the post-election period is the possibility of a provocative weapons test from North Korea to get Biden's attention amid myriad issues that will take top priority in the new U.S. leader's agenda, such as the economy, racial conflict and COVID-19.

"If Biden is elected, the (North Korean leader) Kim Jong-un regime could conduct a provocative test as a 'welcome gift' and demand economic benefits to reduce military tensions," Leif-Eric Easley, a professor at Ewha University in Seoul, told The Korea Times.
