After speaking with South Korean President Park Geun-hye during his trip to Asia, Secretary of State John Kerry told reporters that these past few weeks of North Korean nuclear threats were "unacceptable by any standard" and that the U.S. would never accept the volatile nation becoming a nuclear power.
Kerry also said that the U.S. would defend its allies in the area if it was necessary.
"The rhetoric we are hearing from North Korea is simply unacceptable by any standard," Kerry said. "We are all united in the fact that North Korea will not be accepted as a nuclear power."
North Korea is preparing for a celebration honoring the birthday of its state founder, Kim Il-sung. Some have speculated that the country will use that occasion for some sort of display of military power which is one of the reasons that Kerry is believed to be in the region, Reuters reported.
Reports have surfaced that North Korea may try to launch a medium-range missile after it recently moved its weapons into suitable locations. The country's leader, Kim Jong-un, would be making a "huge mistake" if he went through with a launch, according to Kerry.
"Kim Jong-un's youth and inexperience make him very vulnerable to miscalculation. Our greatest concern is a miscalculation and where that may lead," said a U.S. official in South Korea speaking on the condition of anonymity.
"We have seen no indications of massive troop movements, or troops massing on the border, or massive exercises or anything like that that would back up any of the rhetoric that is going on."
When asked if a war was imminent, the official said: "Not at all.”
