“There are several land mines on the way to the summit between North Korea and the U.S.,” said Chung Dong-young, who served as unification minister during the last progressive administration and is now a lawmaker. “One of those land mines just exploded: John Bolton,” Chung told YTN Radio.

Woo Sang-ho, a lawmaker in Moon’s ruling Democratic Party, agreed. “Bolton’s preposterous ‘Libya solution’ is a red light in North Korea’s summit talks with the U.S. and South Korea,” he wrote in a Facebook post…

“I think a lot of people who were involved with the Roh administration are concerned about Bolton because he was such a neoconservative at the time, and it seems that he hasn’t changed,” said Lee Geun, a professor of political science at Seoul National University. “People are worried that he’s going to interfere and botch the process.”
