(CNN)North Korea's delegation to the Winter Olympics returned to Pyongyang on Sunday, ending a three-day visit that amounted to a remarkable diplomatic breakthrough for the South Korean government but left big questions about whether it could lead to a solution to the decades-long military standoff between the two nations.

A private jet took off from Incheon airport in South Korea Sunday carrying the North Korean delegation whose presence drew the spotlight away from sporting endeavor and raised uncomfortable questions for South Korea's allies. Another 137 members of the North Korean art troupe that traveled south have also returned home.
North Korea's senior leadership left South Korean President Moon Jae-in with a diplomatic conundrum, and his decision could prove to be a defining moment for his leadership -- whether to accept an invitation to Pyongyang for talks with his North Korean counterpart, who presides over a nation where opposition is brutally suppressed, senior officers face execution if they stand in his way and even his own family members are eliminated if they are perceived to pose a threat to his power.
    If the encounter took place, it would be the first between Kim and a South Korean president, and the first North-South summit on the peninsula since 2007, when President Moo-hyun -- whose administration Moon served in -- met with Kim Jong Un's father, Kim Jong Il.
    While the meeting would be a diplomatic coup for Moon -- whose decision to pursue warmer relations with the North stands in stark contrast to his conservative predecessor -- it could strain relations with the United States, which has appeared uncomfortable at the warm welcome afforded to the North Korean delegation over the past few days.
    But US Vice President Mike Pence told Washington Post columnist and CNN political analyst Josh Rogin that he and Moon agreed on terms for further engagement with North Korea, including sitting down with Pyongyang without preconditions.
    Pence called it "maximum pressure and engagement at the same time," Rogin said. The Vice President was also quoted as saying "the point is, no pressure comes off until they are actually doing something that the alliance believes represents a meaningful step toward denuclearization."
    "So the maximum pressure campaign is going to continue and intensify. But if you want to talk, we'll talk," Pence is reported to have said.
    South Korea's Unification Ministry said in response to the Washington Post report that the Moon and Trump administrations' positions on negotiations with North Korea have not changed.
    "The US and South Korea has maintained a consistent stance that dialogue between South and North Korea and the talks between the US and North Korea should follow one after another to induce the denuclearization of North Korea and that continued sanctions and pressure is important," the ministry said in a statement.

    Rare diplomatic honors

    The diplomatic honor bestowed upon North Korea was rare: Moon met Kim Yo Jong, the first member of the North's ruling dynasty to have visited South Korea, four times during the trip. Moon's chief of staff, Yim Jong-suk, held a private farewell dinner for the delegation at a hotel in Seoul on Sunday.
    Kim Yo Jong again sat with President Moon to watch a North Korean art troupe performance in Seoul on Sunday, with both sides expressing hope that the diplomatic overtures would continue after the Games had ended.
    "Always stay healthy. Make sure you visit Pyongyang with President Moon," Kim Yo Jong said to first lady Kim Jung-sook after the concert, according to pool notes from South Korea's Blue House.

    Kim Yong Nam, delegation leader and North Korea's ceremonial head of state, said he shed tears three times during the performance, telling President Moon: "I return with the hope that we will meet again, having created a momentum and opportunity for frequent revisits and exchanged views with the president."
    Moon replied: "Our meeting was precious. Let's two Koreans cooperate to make this meeting embers become a torch."
    South Korea's principal opposition party, the Liberty Korea Party, was not impressed. It warned against agreeing to talks before North Korea scrapped its nuclear program, saying it would only "benefit the enemy".
    "We should firmly keep in mind that any talks where denuclearisation is not a precondition only to buy North Korea more time to complete its nuclear capabilities while they fool us with their peace offensive facade," party spokesman Chang Je-won said, according to Reuters.

    South Korean skepticism

    Despite favorable coverage in the South Korean media that largely ignored the horrors inflicted on North Koreans by Kim's regime, many ordinary South Koreans were skeptical of the North's motives.
    Hundreds of protestors gathered in Seoul on Sunday to vent their anger at what they called the "Pyongyang Games." Some burned North Korean flags and photos of Kim Jong Un at the rally.

    One protester, who gave her name only as Laila, told CNN she was angry at President Moon. "It is the fake peace, this is 'peace Olympics.'"
    "She (Kim Yo Jong) is not charming, she is a dictator's sister," Laila said."She is not looking after North Korean people. They have people hungry in North Korea."
    Others, such as 23-year-old Yoon Jun-young, were angry that that North Korea's participation on the international sporting stage had come without any political concessions. "Her being here is not that bad, but I feel North Korea has shown up to the Olympics without paying," Yoon told CNN during Saturday's hockey match between Switzerland and the unified Korean team.
    Now, South Korea's allies must decide whether to stand back and allow Moon to pursue his policies of reconciliation, or put the screws back on to Pyongyang.
    For its part, Japan has made clear that it favors the swift resumption of joint US-South Korean military exercises, which had been put off until after the Olympics in an effort to smooth the path for North Korea's participation at PyeongChang.
    "Now is not the time to postpone US-South Korea military exercises. It is important to move forward with the drills as planned," Japanese Prime Minister's Shinzo Abe told Moon in what appeared to be an awkward encounter, the Blue House said.
    Moon made it clear that the issue was an internal affair and that it was inappropriate for Abe to have brought up the matter, Reuters reported.
    US Defense Secretary James Mattis also denied rumblings that North Korea could drive a wedge in Washington and Seoul's relationship.
    Mattis said it's "too early to say" whether the situation will continue to remain cool after the Olympics.
    Pence was at pains to insist that Washington and Seoul were on the same page as he returned to Washington from leading the US delegation to the Olympics. "There is no daylight between the United States, the Republic of Korea, and Japan on the need to continue to isolate North Korea economically and diplomatically until they abandon their nuclear ballistic missile program," Pence told reporters on the flight back to the US.
    Just days into the 2018 Winter Olympics, it is clear that it will be remembered as much for political gymnastics as sporting prowess.
