The article is a long story. I've read it. In case you did not bother to read it,
here's my sad and frustrating conclusion after my reading.

It is an amazing secret that US had nuclear weapons nin South Korea for so long.
Even though Korean people did not know, the Russians were informed of it,
and the information must have gone to North Koreans through Russia.

Then, it is no wonder that North Korea had to equip themselves with nuclear weapons
for their defence against the nuclear weapon in South Korea.

So, my conclusion is that the nuclear weapons of North Korea was the fault of US !!
To make the things worse, US told Soviet Union on the presence of nuclear weapon in South Korea.
US is doubly resposible for the nuclear armaments of Norht Korea.

Then, while keeping South Korea from developing it's own nuclear weapons (Jimmy Carter),
US suddenly removed nuclear weapons from South Korea !!

What the fu..... sh.. was that ?? The result is that South Korea got completely fu.... !!
And the South Korea ended up to be the only victim of such mishap of US policy in fareast Asia.
What an idiotic US strategy was that??
US should be fully responsible for the dire defenseless situation of South Korea of today !!

By the way, US has been well known to repeat such stupid strategic blunders all the time.
The world knows so well that US is famous for not "finishing" the job and abandon in the mid-way.
The Vietnam fiasco and mideast blunders are good examples.

So, in other words, in old days, US had made Korean peninsula as the practice target
of nuclear weapons from China, Russia, and even North Korea 
by placing nuclear armements in South Korea.
How nice was that?

I do not want to be anti-US at all and we have to depend on US,
but it seems that we are depending on a friend who is selfish and not smart or loyal.
The sad thing for a small South Korea is that there are not anyone who are better than US !!
이것이 弱者의 悲哀란 것이지요.

About 10+ years ago, I was watching C span, where Prof. Bruce Cummings (of Univ. of Chicago)were giving interview,
concerning recently(then) released reports and minutes of annual USA-Korea Defense ministers Meetings(연례 국방부 장관회의)
of earlier years,probably 80's.
Secretary of Defense and generals of both countries were afraid that that there are too many, small nuclear heads in Korean penninsula.

Some of them(nuclear heads) could be easily fired from helicopters and ,if I remember correctly,some could be fired from an infantry soldier.
They were really afraid of individual mistakes and mis-judgements from low level officiers or soldiers, in the discussed minutes of those meetings.

"김정권이 핵을 가지는 것이 미국때문이라고 하는 것은 궤변이 아닐가요?"
본인 생각에는 이것이 궤변이 아니라고 생각합니다.
북한은 당연히 자기네의 "self-defense against US"로 핵무기의 소유를 원하게 된것이지요.
북한은 언제나 미국과 남한의 북침 위협을 느끼며 살고있으니, 핵무기의 소유가 일석이조의
유리한 정치, 군사적 위치를 마련랄수있었던 것이지요.
더구나 미국자신이 북한을 위협했던것은(핵무기로) 사실이였지요.
만일 미국이 남한을 전혀 돌보지 않었다면, 북한은 핵무기 소유에 크게 관심이 없었을지 모르지요.

하여간, 이렇게 알고있는것이 우리 또는 미국의 미래에 유리한것으로 봅니다.
미국도 자신의 세계적 신임을 잃고있다는것을 As soon as possible 로 깨달아야 되겠지요.
Dr. Ohn의 의견처럼 교만은 곧 수치를 불러오게 마련이지요.
그 좋은 예가 Vietnam전쟁... 약소국인 Vietnam에 대한 교만이 결국은 치욕의 패배를 불러들인것입니다.

남한은 운명적으로 미국에 의존해서 사는 나라로서 미국의 패배를 원하지 않지요.
더구나 Trump같은 자들이 미국을 통치한다면 미국의 교만은 하늘을 찌를것 아닙니까?
그러다 보면 언제고 반듯이 치욕을 보게될것입니다. 우리는 그런일이 생기는것을 원하지 않기에
은근히 걱정하고 있는것이지요.

좀 과장된 얘기 같지만, 만일 Trump가 대통령이 된다면....
부지런히 한국이나 Canada의 passport를 준비함이 어떨지요?
우리는 반세기전에 태평양을 건너 유랑의 길을 떠났지만,
이제 다시 어디로 유랑의 길을 떠날것인가요?
이것이 과연 괴변일가요?
운명의 장난은...You never know.
