When President Donald Trump and North Korean leader Kim Jong Un signed a statement Tuesday committing to establishing new, peaceful relations, they also agreed to resolve an issue as old as the Korean conflict itself.
The unprecedented encounter in Singapore Tuesday saw the leader of the world's most powerful democracy shake hands with the third generation scion of a dynastic dictatorship, standing as equals in front of their nations' flags. "The Marshall of North Korea (Kim Jong-un) trusts me".
Pyongyang has reason to feel confident after the meeting which was a major coup for an isolated and heavily sanctioned regime that has long craved global legitimacy.
Trump's diplomacy "sends all the wrong messages to China, North Korea and Russian Federation", said Malcolm Davis, a senior analyst at the Australian Strategic Policy Institute.
"We would like to seek an understanding of this between Japan, the US and South Korea", Japan's defence minister, Itsunori Onodera, said.
"So many people have talked to me about it", Trump told reporters.
Following their historic summit on Tuesday, Trump had said he would like to visit the North Korean capital Pyongyang "at the appropriate time", and that Kim would "absolutely" would be invited to the White House. "If our alliances are getting weaker and we're not going to do military exercises, where is the pressure?"
Ending the drills "is in excess of all expert consensus, South Korean requests, and even a close reading of North Korean demands", said Adam Mount of the Federation of American Scientists.
It said that Kim and Trump had "shared recognition to the effect that it is important to abide by the principle of step-by-step and simultaneous action in achieving peace, stability and denuclearization of the Korean Peninsula".
It added that denuclearization on the Korean peninsula would be dependent on the two sides "refraining from antagonizing... each other out of mutual understanding".
Before he ran for president in the 2016 election, Mr Trump was a businessman with a long career in entertainment, presenting The Apprentice reality TV show for several years.
"The World has taken a big step back from potential Nuclear catastrophe!" The hostages are back home with their families.
The Singapore summit was a potentially legacy-defining meeting for both men - comparable to president Richard Nixon's 1972 visit to China, or Ronald Reagan's 1986 summit with Mikhail Gorbachev in Reykjavik.
Trump and Kim said they "commit to recovering" the remains of U.S. service members killed in the war of 1950-1953, "including the immediate repatriation of those already identified".
World powers from China to Japan, the European Union and Russian Federation welcomed its outcome - while cautioning it was only the first step towards resolving the nuclear stand-off with Pyongyang.
The US has long held the view that North Korea's illegitimate military activities can't be traded away for its right to do legitimate military activities.
Mr Turnbull said the promise was "obviously part of the negotiating tactic" and emphasised the "alternative vision" Mr Trump was offering the North Korean regime.
KCNA said the two leaders ate and walked together, "deepening friendly feelings" towards each other.
Trump has said repeatedly that Tuesday's summit was only the start of a process and that the USA would not ease up pressure on the North - including a crippling sanctions regime - until its goal of North Korea's "complete, verifiable, irreversible denuclearization" is reached.
Ms Bishop has cautiously welcomed the overall progress in the summit but warned North Korea's denuclearisation must be thoroughly verified and dismissed Mr Trump's concession on military exercises.
Japan, the chief US ally in the region, got none of what it wanted - Kim made no promise to address the issue of Japanese citizens abducted by North Korea, and he offered no limits on his ballistic missile programs.
