SEOUL Arms control experts estimate that the dismantlement of North Korea's nuclear program could take a decade to complete, and cost $20 billion, if a nuclear agreement is reached between U.S. President Donald Trump and North Korean leader Kim Jong Un when they meet in Singapore on June 12. "The hard work has not yet begun, and it is gong to take sustained energy on the part of the United States, South Korea, Japan, China and North Korea. It's going to be a multiyear long process," said Daryl Kimball, the executive director of the Arms Control Association in Washington. President Trump has said he expects a "very positive result" from the North Korea nuclear summit, but he also said it will likely be the beginning of a process to resolve differences over the extent of the North's denuclearization, and the specifics regarding what sanctions relief, economic aid and security guarantees would be offered in return. U.S. Defense Secretary Jim Mattis said on Sunday that North Korea would only receive sanctions relief after it takes "verifiable and irreversible steps to denuclearization." This position aligns closer to the Kim government's stance that denuclearization measures and concessions be matched action for action. And it backs away from demands made by some in the president's national security team that Pyongyang quickly and unilaterally dismantle all its weapons of mass destruction before any concessions would be offered. North Korea is estimated to have 20 to 80 nuclear warheads, both known and covert nuclear research and processing sites, and thousands of ballistic missiles that can be launched from mobile vehicles, and submarine based launchers have been tested in recent years. With such an extensive nuclear arsenal it could cost $20 billion to achieve the U.S. goal of complete, irreversible, and verifiable nuclear dismantlement (CVID), according to a recent study conducted by Kwon Hyuk-chul, a Kookmin University professor of security strategy. Kwon based his assessment in part on past nuclear deals... Question: Who expects a very positive step from the nuclear summit? Options: A. Mattis B. Daryl Kimball C. Trump D. not enough information === The correct answer is
C

SEOUL North Korea's sudden threat to pull out of the upcoming summit with the U.S. raises new doubts of whether a denuclearization deal is possible. North Korean leader Kim Jong Un agreed to meet with U.S President Donald Trump in Singapore on June 12 to work out an agreement to end the North's nuclear program in exchange for security guarantees and an end to punishing international sanctions. But on Wednesday North Korea's Vice Foreign Minister Kim Kye Kwan released a statement through the state-run KCNA news agency that criticized "unbridled remarks" made specifically by the U.S. president's National Security Adviser John Bolton demanding that Pyongyang completely decommission its entire nuclear arsenal, along with its ballistic missile program and chemical weapons stockpile, before receiving any compensation or concessions. He expressed "indignation" at the U.S uncompromising position and said North Korea might pull out of the Trump-Kim summit, unless the Trump administration acts with "sincerity" to improve relations through dialogue. "If the United States is trying to drive us into a corner to force our unilateral nuclear abandonment, we will no longer be interested in such dialogue and cannot but reconsider our proceeding to the North Korea-U.S. summit," the statement said. The vice foreign minister also said it was "absolutely absurd" that Bolton would compare Libya's experience dismantling its relatively rudimentary nuclear program as a model for dealing with the North's more advanced and expansive capabilities. He also denounced the Trump administration for "miscalculating the magnanimity" of Kim Jong Un's decision to suspend further nuclear and missile tests, and his willingness to engage in nuclear talks, as "signs of weakness," that were the result of what the U.S. administration has dubbed its "maximum pressure" campaign that led international efforts to impose punishing sanctions banning 90% of North Korean trade. The vice minister's remarks came shortly after the North abruptly canceled...

U.S. President Donald Trump said Saturday that he had instructed his representatives not to sign a communique by all seven leaders attending the G-7 summit in Canada, citing statements by Canada's Prime Minister Justin Trudeau made after he left. "Very dishonest and & weak," Trump tweeted in response to Trudeau's remark that the new U.S. tariffs on aluminum and steel were "insulting." "Based on Justin's false statements at his news conference, and the fact that Canada is charging massive Tariffs to our U.S. farmers, workers, and companies, I have instructed our U.S. Reps not to endorse the Communique as we look at Tariffs on automobiles flooding the U.S. Market!" Trump added. "International cooperation cannot be dictated by fits of anger and throwaway remarks," French President Emmanuel Macron's office said in a statement about Trump's withdrawal from signing the communique. The statement also said Trump's action is a display of "incoherence and inconsistency." "Germany stands by the jointly agreed communique," Germany spokesman Steffen Seibert said in a statement. Trudeau closed the summit Saturday by refusing to budge on positions that place him at odds with Trump, particularly new tariffs on steel and aluminum that have irritated Canada and the European Union. He said in closing remarks that Canada would proceed with retaliatory measures on U.S. goods as early as July 1. "I highlighted directly to the president that Canadians did not take it lightly that the United States has moved forward with significant tariffs," Trudeau said in the news conference following the two-day summit. "Canadians, we're polite, we're reasonable, but we will also not be pushed around." British Prime Minister Theresa May echoed Trudeau, pledging to retaliate for tariffs on EU goods. "The loss of trade through tariffs undermines competition, reduces productivity, removes the incentive to innovate and ultimately makes everyone poorer," she said. "And in response, the EU will impose countermeasures." Trudeau and May also bucked... Question: Where did Trudeau make his closing statement? Options: A. United States B. not enough information C.
