Hillary Clinton recently weighed in on the Trump administration's actions relating to North Korea.

Hillary Clinton is reportedly concerned that the Trump administration lacks the personnel capabilities needed to handle discussions with North Korea. 
According to the AFP, the former Secretary of State told the Dutch publication Algemeen Dagblad in a recent interview, "If you want to talk to [North Korean leader] Kim Jong Un about his nuclear weapons you need experienced diplomats...These are people familiar with the dossiers and who know the North Koreans and their language." 
However, she pointed out that there is currently a shortage of such veteran staff at the U.S. State Department and, in her words, "the danger is not being recognised by the Trump government." 
Her warning has been echoed by former U.S. ambassador to South Korea Alexander Vershbow, who wrote in an Axios op-ed about the proposed talks with North Korea: "It is worrisome...that the U.S. government, more than a year into Trump's presidency, does not have a high-level team of experienced professionals to lay the groundwork." 
"Assembling a qualified team and defining a negotiating strategy in coordination with U.S. allies, is now the most urgent priority if these potentially historic talks are to succeed. This is not the time to wing it," he added. 
The State Department recently lost a key member of its team on North Korea after Joseph Yun, a career diplomat for more than 30 years, decided to retire, reports NPR.
The Trump administration has also not yet named a U.S. ambassador to South Korea. 
Concerns about the diplomatic capabilities are being raised after the White House announced that President Trump plans to meet with Kim Jong Un.
