Earlier North Korean leader Kim Jong Un declared that the United States should make the "right choice" to prevent a conflict between their two countries, while ordering his generals to prepare for a possible military strike.
He said no US military action on the Korean Peninsula could be taken without Seoul's consent.
"Kim Jong-un, the world always thought he was not a responsible leader", said Ellison.
"(North Korean leader) Kim Jong Un is a bully with some very strong weapons...
Meanwhile, North Korea said it won't fire a missile at the USA territory of Guam, posting a statement on the matter on Monday night, August 14.
"North Korea seems to be hosting what appears to be a meeting of foreign diplomatic missions' chiefs after calling its ambassadors to major countries back to Pyongyang", Yonhap News Agency news agency reported.
On Tuesday, US Secretary of Defense Jim Mattis was asked whether he believed Kim was holding off on a missile launch targeting Guam and what the US would do if such a launch took place.More news: Not Surprising If North Korea Tests Missile Again — CIA Chief
China, North Korea's most important ally, said Monday that it will stop importing North Korean goods including iron ore, coal and fish from midnight on September 5.as part of United Nations sanctions imposed on Pyongyang over its nuclear and missile program. Donald Trump couldn't resist one-upping North Korea's leader with his own boast: "North Korea best not make any more threats to the United States".
One large map appeared to show a straight line between northeastern North Korea and Guam, a United States territory in the western Pacific that is home to American military bases. But it also reported that leader Kim Jong Un would watch US conduct before giving his orders for the test. The U.S. goal, they wrote, is a denuclearized Korean peninsula.
"But, at the end of the day, North Korea is not going to bite on engagement unless the US puts something significant on the table", Gause added.
Moon, in a televised speech Tuesday on the anniversary of World War II's end and the Korean Peninsula's liberation from Japanese colonial rule, said Seoul and Washington agree that the nuclear standoff should "absolutely be solved peacefully".
Past exercises, meant to deter a North Korean attack, "are believed to have included 'decapitation strikes'-trial operations for an attempt to kill Kim Jong-un and his top generals", according to the Guardian.
"It's important for people like me in our community to educate people - what is our situation in terms of our American citizens who can't vote for a president who takes us to war?"
Mattis and Tillerson said the United States favors a diplomatic solution to the nuclear stand-off, especially with help from China, though they stressed diplomacy is "backed by military options".
"(North Korea's) nuclear ambitions create a much larger threat for states in its region, giving them an incentive to intervene before (North Korea) presents a credible threat to their national security interests", she said.
