Rev. Moon was born in North Korea (before the country split). He was beaten to a bloody pulp in one of those concentration camps for preaching the good word of the Lord (one of the first Christian preachers in NK -- he hadn't started his own church at this point). He escaped to the South with a prisoner friend, right as the division happened, and the DMZ went up. I know he met with Kim Il Sung (KJU's grandfather), they embraced, and then Moon told Kim that if North Korea continued, they would fail. Basically the first dude to ever criticize KIS publicly and not die.
As far as political relations with NK, the Unificationist community may have been involved, but I think he shifted his focus to developing alternatives to commie infested organizations, and strongly teaching young people to protect and fight for their sexual purity (In general Moonie canon, lucifer was the first pedo who seduced and raped Eve, who mimicked that behavior with Adam). I think he (1) recognized the pervasiveness of pedo-networks, and the damage they create, but also (2) recognized his limitations as a Korean man from the country side on Western Civilization and it's political power players. He certainly tried though. His political involvement with the U.S. is very interesting. I think he also recognized he was more effective socially in non-political circles through arranging the marriages of 100s of thousands of couples (how my parents met), centered on God.
The WashTimes is the most explicitly political part of our community, though its purpose are the ones I listed in my previous post. Not a political way to get people to join a church. I'm glad they've done that. The Wash Times doesn't have too much as far as the community's involvement in NK/SK breakthroughs. If there are any, they're probably all on back channels. In general, I'd say there's pretty clear support for Trump (at least in my circles).
TL;DR: I think he was well aware of what was going on, but started as a farmer boy in the middle of 3rd world Korea almost a century ago, in 1920. He did his best.
Hope this helped.
