I used to use a similar worldwide photo produced by NASA as a PC wallpaper. NASA creates maps without clouds by using composite photos. The darkness of North Korea stood out like a sore thumb.
About 5 years ago I attended a Baptist men’s church retreat where the featured speaker was Mark Bailey, the president of Dallas Theological Seminary. He told us that he had visited Donald Rumsfeld’s office and had seen the NASA photo cropped to show just North Korea. The difference between north and south is really stark.
I’ve seen the older photo with the lines drawn. I just thought it was interesting that the mainstream media is now paying attention to this subject.
