But in a rare move the dictator tempered his bellicose rhetoric with the suggestion he may send a North Korean delegation to the Winter Olympics when they are held in South Korea.
North Korean leader Kim Jong-un on Monday claimed he has a nuclear button installed in his office and is ready to strike at any time. Relations between the Koreas have plunged as North Korea has expanded its weapons programs amid a hard-line stance by Moon's conservative predecessors.
Kim's comments on Monday were the first indication of North Korea's willingness to participate in the Winter Games, which run from February 9 to 25. In the address, Kim celebrated the completion of North Korea's nuclear weapons and ballistic missile programs, offered to enter conditional talks with South Korea with the offer of potentially sending a delegation to the upcoming Pyeongchang Winter Olympics in South Korea, and condemned global sanctions. The implication of the statement was clear: Kim, and only Kim, could launch North Korea's nuclear weapons.
"The change from the (Kim's) previous dark Maoist suits to a softer toned grey Western-style suit likely aimed to underpin peace which Kim stressed in his address, and reflected a relaxed state of mind that probably came with the completion of the North's nuclear power", the Institute said.
North Korea has rattled the global community in recent months with multiple missile launches and its sixth and most powerful nuclear test - purportedly of a hydrogen bomb.More news: Bill O'Brien returning to Texans is best for DeShaun Watson
"Kim Jong Un's strategy remains the same".
But he also hinted at diplomatic overtures to South Korea amid increasingly crippling sanctions.
Referring to the Olympics, he said later: "We're willing to take necessary steps including sending our delegation, and for this, the authorities from the North and South could urgently meet".
'The Winter Olympic games that will be held soon in the South will be a good opportunity to display the status of the Korean nation and we sincerely wish that the event will be held with good results, ' he said.
The tyrant warned America that it can "never start a war against me and our country" and insisted his nukes are now a reality, not a threat.
"The U.S. should know that the button for nuclear weapons is on my table", he said during the speech, as provisionally translated by the AP. Yet he insisted that both North and South Korea "should make efforts".
