At the end of the North American summit in Singapore on June 12, 2018, North Korean State Security Adviser John Bolton revealed that North Korean State Council Chairman Kim Jong-un suggested that US President Donald Trump could review it at the end of the talks.

Sumi Terry, a senior researcher at the Center for Strategic and International Affairs, has published three meetings in the memoirs of the former aide, Bolton's upcoming book,'Room where it happened', the Singapore Summit, the Hanoi Summit in Vietnam at the end of February last year, and the'Panmunjom Meeting' at the end of June last year. We uploaded some of the memoirs from the North American summit on their Twitter.

According to a summary released by Senior Researcher Terry, Chairman Kim Jong-un said he was pleased at the Singapore summit that he and Trump agreed to follow the "action versus action" approach.

'Action vs. action' refers to the phased approach North Korea has demanded in relation to denuclearization and countermeasures, and is far from the official position of the United States.

In response, Kim asked if UN sanctions could be lifted in the next order, and Trump said he was open and said he wanted to think about it.

As a result, Chairman Kim is said to have appeared in a memoir saying he left with optimism.

According to a memoir introduced by Senior Researcher Terry, when President Kim said the United States wants to reduce or abolish US-ROK military training, President Trump says he will ignore generals and do so.

This was not discussed with Secretary of State John Kelly at the meeting, Secretary of State Mike Pompeo, former Aide Bolton, and Defense Secretary James Mathis, who was not in the meeting, and had no consultation with South Korea.

Memoirs of former aide Bolton also included a story behind the second North American summit in Hanoi, Vietnam.

President Trump had three options at the time of the Hanoi meeting: Big Deal, Small Deal, and'Walk Outside the Negotiation Hall'. Among them, Small Deal was not dramatic and he refused because he did not want to give up sanctions. We delivered contents.

The big deal didn't happen because Kim hadn't made a strategic decision to give up nuclear weapons, and the only thing left was the option to walk out of the negotiations.

President Trump is said to have been prepared for the option to walk in accordance with the philosophy that'you kick a woman before the woman kicks you', Bolton said in a memoir.

A former Bolton adviser said in Hanoi that the agreement was close, but Kim refused to give anything other than Yongbyon, and President Trump pleaded for more, but Kim refused.

In Hanoi, President Trump is said to have been in a memoir saying he stayed up all night watching a hearing by former private lawyer Michael Cohen, who turned his back on him.

President Trump was annoyed and wondered,'If I settle a small deal or walk out of the negotiations, it would be a bigger knight.'

At the end of June last year, the meeting at Panmunjom was said to be contained in a memoir that was entirely the idea of ​​President Trump.

President Trump came up with the idea during his meeting with German Chancellor Angela Merkel at a meeting in 20 major countries held in Tokyo, Japan, and was amazed at the ex-Bolton's aide as well as acting as White House secretary at the time of Mick Mulvenini.

Secretary of State Pompeo also said that he saw "no value here" and was reportedly mentioned in a memoir by former adviser Bolton.

According to the US CBS Broadcasting, former aide to Bolton said he knew that he and Ms. Vilnius at the time saw a tweet that Trump invited Chairman Kim to be demilitarized. "Mulvanini looked embarrassed like me. I thought it was a throw,” he wrote in the memoirs, saying, “I was embarrassed that the tweet I saw wasn't a big deal led to a real summit.”

Former aide adviser Bolton said that President Trump said, "Chairman Kim has requested the 3rd summit," and "Chairman Kim was very keen to meet me." "It is certain," said President Trump because he wanted to meet more.
