한국사람이 일본사람을 미워하기 시작한 계기는 임진전쟁이었다.

전쟁은 7년동안 계속 되었다. 전쟁 후 조선의 인구는 백만이 줄었고

전답 2/3가 황폐화 된 것으로 추산 하고 있다. 

유크레인은 서방과 러시아 중간에 끼어 있다. 한국이 일본과 미국

의 태평양 세력과 대륙의 중국, 러시아 사이에 끼어 있는 것과 

비슷하다. 이를 어려운 말로 지정학적 위치라고 한다. 

유크레인이 친러 성향의 동부와 친서방 성향의 서부가 분안될 가능

성이 많다. 한국은 이미 친대륙의 북쪽과 친 태평양의 남쪽이 갈라

져 있다. 크게 보면 일본은 적이 아니고 우방이다. 그러나 앙클 쌤이 

맺어준 일시적인 인연일 뿐이다.

https://en.wikipedia.org/wiki/Chernobyl_disaster

The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union.^[1][2] It is considered the worst nuclear disaster in history both in cost and casualties.^[3] It is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima Daiichi nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019, adjusted for inflation.^[4][5]

https://en.wikipedia.org/wiki/Nuclear_weapons_and_Ukraine

Prior to 1991, Ukraine was part of the Soviet Union and had Soviet nuclear weapons in its territory.

On December 1, 1991, Ukraine, the second most powerful republic in the Soviet Union (USSR), voted overwhelmingly for independence, which ended any realistic chance of the Soviet Union staying together even on a limited scale.^[1] More than 90% of the electorate expressed their support for Ukraine's declaration of independence, and they elected the chairman of the parliament, Leonid Kravchuk as the first president of the country. At the meetings in Brest, Belarus on December 8, and in Alma Ata on December 21, the leaders of Belarus, Russia, and Ukraine formally dissolved the Soviet Union and formed the Commonwealth of Independent States(CIS).

After the dissolution of the Soviet Union, Ukraine held about one third of the Soviet nuclear arsenal, the third largest in the world at the time, as well as significant means of its design and production.^[2] 130 UR-100N intercontinental ballistic missiles (ICBM) with six warheads each, 46 RT-23 Molodets ICBMs with ten warheads apiece, as well as 33 heavy bombers, totaling approximately 1,700 warheads remained on Ukrainian territory.^[3] Formally, these weapons were controlled by the Commonwealth of Independent States.^[4]In 1994 Ukraine agreed to destroy the weapons, and to join the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).

Denuclearization

International relations theorist John Mearsheimer predicted a Ukraine without any nuclear deterrent was likely to be subjected to aggression by Russia, but this was very much a minority view at the time.^[8]

A 2016 study argues that the denuclearization of Ukraine was not a "stupid mistake" and that it is unclear that Ukraine would be better off as a nuclear state.^[9] The study argues that the push for Ukrainian independence was with a view to make it a nonnuclear state.^[9] The United States would also not have made Ukraine an exception when it came to the denuclearization of other post-Soviet states such as Belarus and Kazakhstan.^[9] The deterrent value of the nuclear weapons in Ukraine was also questionable, as Ukraine would have had to spend 12 to 18 months to establish full operational control over the nuclear arsenal left by the Russians.^[9] The ICBMs also had a range of 5,000–10,000 km (initially targeting the United States), which meant that they could only have been re-targeted to hit Russia's far east.^[9] The air-launched cruise missiles (ALCMs) left by the Russians had been disabled by the Russians during the collapse of the Soviet Union, but even if they had been reconfigured and made to work by the Ukrainians, it is unlikely that they would have had a deterrent effect.^[9] Had Ukraine decided to establish full operational control of the nuclear weapons, it would have faced sanctions by the West and perhaps even a withdrawal of diplomatic recognition by the United States and other NATO allies.^[9] Ukraine would also likely have faced retaliatory action by Russia.^[9] Ukraine would also have struggled with replacing the nuclear weapons once their service life expired, as Ukraine did not have a nuclear weapons program.^[9] In exchange for giving up its nuclear weapons, Ukraine received financial compensation, as well as the security assurances of the Budapest Memorandum.
