which resulted in a no-deal outcome for the summit. According to Jenny Town, Washington based, think-tank and North Korean expert, "it's Bolton's proposal in 2004, has been rejected more than once and, to bring it up again… would rather be insulting.” She also said that the US should have learned that this wasn't effective diplomacy, and shows they haven't learned how to properly negotiate. Former special assistant to President Ronald Reagan, and a senior fellow at the Cato Institute, Doug Bandow, President Trump was demanding unrealistically for Chairman Kim Jong Un to dismantle all his nuclear facilities, whereas Chairman Kim was only agreeing to shutting down the YongByon Nuclear facility in exchange for a partial lifting of a few UN sanctions against his country. Asking continuously for an all nukes for sanctions deal is deemed as malicious in its intent and illogical. Douglas Dillon Professor of Government at the Harvard Kennedy School, and former director of Harvard's Belfer Center, Graham T. Allison, believes that the Hanoi summit is not a whole failure, despite some public opinion, and even compared this to the Reagan-Gorbachev era. President Reagan also had to deal with negative public opinion regarding his dealings with the USSR, but he was able to remove all of the Soviet Union's intermediate nuclear-armed missiles with an INF deal. Compared to the USSR, North Korea is also communist country, but President Trump was able to deal with the top leader of North Korea, Chairman Kim, something neither Bush nor Obama were able to do in their combined 16- year term. According to Abby Bard, a research associate for Asia policy at the Center for American Progress, President Trump's and Chairman Kim's teams need critical space between them to build trust and verify the intentions between the two parties. Working level meetings between both teams are needed to arrange the details that would result in bigger bargains without miscalculations and misunderstandings. In order for the two leaders to reach a deal, their diplomatic teams need to work together. On September 10, Trump sacked the national security adviser John Bolton as he strongly disagreed with John Bolton's suggestion about applying Libyan model to North Korea nuclear deal and mentioning Muammar Gaddafi. However, Bolton himself claims he was not sacked but resigned. Donald Trump selected hostage negotiator of DPRK Robert C. O'Brien as the new U.S. national security adviser.
