Wonder if this has to do also with the idea that Moon is more than willing to re-establish relations with Kim Un and his desire to see Thadd removed?..Thus we have to have our own focus on N.Korea as it remains a threat to the US. I don’t especially trust Moon is all that friendly toward the US....he wants to control all decisions even though he “politely” says he’ll converse with the US.
I don’t generally trust Asians anyway. .....it’s a culture thing in how they communicate.
Of course, what he says is a lie. He is a proxy of Kim Jong-un. I wouldn't rule out that he would manage to push S. Korea into a target of secondary sanction. He has a grand plan of reviving S. Korean investment into N. Korean industrial park. He wants to vastly expand the industrial park(an area which houses S. Korean factories,) up to 16,000 acres. Kaesung Industrial Park which was shut down in previous government has an area of 6,500 acres.
If you have time, look up the background of his right-hand man and his Chief of Staff, Lim Jong-suk. The man was home-grown N. Korean operative who actually met Kim Il-sung twice while he was an operative trying to overthrow the 'puppet regime of American Imperialist.' He never renounced his past. The fanatics do not change color. Most of the times, they can't because their ideology is so ingrained. Their facade and packaging can be changed.
I don't usually go into details of S. Korean politics, because it is so much more work than writing about N. Korea. People are lot more ignorant on this subject than what goes on in N. Korea. So it takes too much time to engage people who know little or have outright misconception. For N. Korea, at least they can read a lot about the country. Americans can know about the family tree of Kim Dynasty or pecking order of N. Korean officials. Almost nobody knows about political map of S. Korean political factions, especially breakdown of all S. Korean leftwing organizations.
It will be interesting. Don't be surprised if the new S. Korean government defies your expectation.
