A spokesman for the Strategic Force of the Korean People's Army, or KPA, told North Korea's state-run media the KPA is "carefully examining the operational plan for making an enveloping fire at the areas around Guam with medium-to-long-range strategic ballistic rocket Hwasong-12 in order to contain the USA major military bases on Guam".
Moon, who took office in May, made his most ambitious plea for engagement two days after North Korea test-launched its first intercontinental ballistic missile last month.
The people of Guam woke up Thursday to another pointed threat from Pyongyang, which vowed to complete a plan to attack waters near the island by mid-August - adding a timeline to a threat from a day earlier that North Korea would create an "enveloping fire" around Guam.
The country's military leaders are finalizing a plan to present to Kim Jong Un in mid-August to fire four intermediate-range Hwasong-12 missiles over Japan to land less than 25 miles (40 kilometers) from Guam, state media reported Thursday.
South Korea and Japan warned North Korea that it would face a strong response if it carried through with a threat to launch a missile toward Guam. In 2013, state media cited leader Kim Jong Un as having ordered his military to prepare plans on launching strikes on US military bases in Guam, Hawaii and South Korea as well as the American mainland.
The younger Kim is more determined to intimidate his neighbors than his father was, and is also a lot sassier, handing a threat right back to Donald Trump, whose authoritarian approach seems to have backfired.
The forum members also urged North Korea to comply with obligations stated in the United Nations Security Council resolutions.
North Korea wants an end to annual military drills between the United States and South Korea that it condemns as invasion rehearsals, and the removal of tens of thousands of US troops stationed in the South.
The term "locked and loaded", popularized in the 1949 war film "Sands of Iwo Jima" starring American actor John Wayne, refers to preparations for shooting a gun.
"Koreans used to be numb to North Korea's threats".
Residents of the tiny territory - just 12 miles at its widest point and circled with lovely beaches - find themselves again caught in the middle of a war of words as a volley of hostile rhetoric was launched between North Korea and the United States, including pointed threats of nuclear action. While the latest rhetoric causes concern, that's as far as it goes, he said. "Hopefully Kim Jong Un will find another path!" Hawaii is about 4,000 miles (6,500 km) to the east. Inflammatory rhetoric on both sides will make that more likely.
Seoul is expanding its participation in a nationwide civil defence drill, set to take place on August 23, Shim Kang-cheon, a local Seoul government official, told Reuters.
Dubbed the "tip of the spear", Guam is a key to the USA military's forward deployed presence in the Pacific and is home to thousands of American service members and their families.
"I feel it's different this time", said Yoon, who's been in the business since 2004. Its natives are US citizens by birth.
USA financial markets took the rhetorical escalation in stride on Friday.
Trump said hours later, "Let her speak for Germany".
"For me because I'm a father, so it's really concerning, you know, I wish it didn't have to come to that", he said.
