SEOUL, SOUTH KOREA The U.S. election calendar could be a key factor in determining the scope and timing of a potential deal to end the North Korean nuclear program. Planning is progressing for both the upcoming summit between North Korean leader Kim Jong Un and South Korean President Moon Jae-in at the end of April and the expected meeting between U.S. President Donald Trump and Kim in late May or early June. President Trump said Tuesday that there had been talks at "extremely high levels" between his administration and the North Korean government. Later it was reported that Mike Pompeo, the director of the Central Intelligence Agency and a secretary of state nominee, met recently with Kim Jong Un in Pyongyang. Trump also noted the talks have been marked by "a lot of goodwill" and that "there has been a major change in terms of North Korea's behavior," since Kim's Olympic outreach this year, in which he sent a large delegation to the Pyeongchang Winter games in South Korea, suspended nuclear and missile tests, and expressed a willingness to engage in denuclearization talks. The turn toward diplomacy has reduced, for now, the potential for conflict over the North's accelerated efforts last year to develop an operational nuclear-armed intercontinental ballistic missile that can reach the U.S. mainland. The North Korean leader's decision to engage in denuclearization talks was likely motivated by both Trump's "maximum pressure" campaign, which increased sanctions and the threat of military action against the North, and by South Korean President Moon's reassuring outreach efforts to improve inter-Korean relations. Trump's motivation in pursuing a nuclear deal with North Korea, in addition to resolving a growing national security threat, could also have a political component. According to North Korea analysts at the Sejong Institute in South Korea, the Trump administration is likely calculating how achieving such an agreement could help boost the president's chances for re-election in 2020. "If I were Trump, I... Question: When was there a major change in North Korea's behavior? === The answer to the above question is

A: After Kim sent a large delegation to the Olympics

The sweet taste of cold and wood smoke hung in the air. Marlin rode low in the saddle, his shoulders curled against the hungry wind. His hat was pulled down tight and his eyes didn't move as he passed the crude shacks at the edge of town. He tied his horse in front of the saloon, unwinding his long body as if a sudden movement might snap it. He turned down the collar of his greatcoat and checked to make sure his big Army Colt was loose in its holster. The saloon door was a single chunk of white pine, still oozing sap, and he had to put his shoulder to it to force it open. The long room inside was quiet, and not much warmer than the street. Clusters of people sat nursing coffee and drinks, talking quietly if they talked at all. Marlin spotted a few farmers the railroad had brought in from Europe: rounded hats, nervous eyes, skin as red as blood. At the far end of the room a half-dozen cowboys turned over cards with patient boredom. Marlin walked up to the bar. "Whiskey," he said, and when the drink came he tossed it straight down and felt it pull his lips into a grimace. He nodded for a refill. When he turned to face the room they were all watching him. "I'm looking for a man named Kraamer," Marlin said. "Anybody here know of him?" One of the cowboys turned casually and rang the spittoon with a stream of tobacco juice. Marlin knew the long, thin face from somewhere, the blond hair that fell limply to his shoulders. He smiled at Marlin and showed his brown-stained teeth. Marlin felt the lines in his own face, the gray in his hair, the chill in his bones. He was too old for this. He set a half dollar on the bar and started for the door. "Don't get in a huff," the bartender said. Marlin looked back. "Kraamer lives about a mile west of town. Follow the railroad and take the first trail south."

Q: A funeral for Zbigniew Brzezinski, the national security adviser to President Jimmy Carter and a noted foreign policy expert and thinker, will be held Friday at St. Matthew's Roman Catholic Cathedral in Washington, D.C. Brzezinski died May 26 in Virginia. He was 86. In a statement, Carter called Brzezinski "a superb public servant" as well as "brilliant, dedicated and loyal." Along with Henry Kissinger, Brzezinski helped shape U.S. foreign policy with a lasting impact, while also serving as an adviser to Presidents Lyndon Johnson and John F. Kennedy. One of his most well-known accomplishments came in 1978, when Brzezinski helped President Carter reach an agreement between Israeli Prime Minister Menachem Begin and Egyptian President Anwar Sadat to secure the Camp David peace accords between the two countries. He also was involved in making other major U.S. foreign policy decisions during the Carter administration, including negotiating the Panama Canal Treaty, arming mujahedin in Afghanistan to fight the Soviet invaders and planning a failed mission to rescue 52 American hostages held in Iran. Alexander Vershbow, a former deputy secretary general of NATO and former U.S. ambassador to Russia, told VOA Brzezinski's wisdom also guided U.S. and NATO policy in the post-Cold War period. "On one hand, listening to the appeals of countries like Poland, like Czechoslovakia, like Hungary, to become part of the Western family, which they were denied 70 years ago ... but also reaching out to Russia, and trying to help Russia become an integral part of the European family, the common European house, as [former Soviet leader Mikhail] Gorbachev described it," Vershbow said. Following his work in the White House, Brzezinski continued to be an influential voice on foreign policy matters. He served as a counselor and trustee at the Center for Strategic and International Studies and a professor at Johns Hopkins University. Brzezinski went on to ruffle the feathers of Washington's power elite with his 1983 book, "Power and... Question: President Carter probably believes that: === The answer to the above question is
