And the Inca was glorified for this.
Well of course they were!
Anyway, I'm quite familiar with the "microclimates." I've hiked the Inca Trail, 45 km from Sacsayhuaman to Machu Picchu. Four days of elevation changes from 200 m above mean sea level to 4500 m. Dress in layers. Get ready to eat sh**t. Fish heads, chicha, or whatever you can scrounge up along the way. 70-pound Jansport backpack with tent and sleeping bag and lots of cocaine (which rather helps with the hike.) I've also spent several weeks in Peru, Bolivia, and Ecuador visiting the local museums and, although I'm no expert on pre-columbian American history, I have read Hiram Bingham and some more modern texts on the subject. I reckon myself fairly well versed on the Inca legal system. Adultery? execution. Insubordination? execution. And the preferred method was rather interesting too.
Still, I hardly think it reminiscent of the North Koreans. Maybe just because I'm fairly ignorant of Korea and its recent history. Outside of the terms I've learned from my son's Tae Kwon Do class--from that I can count from one to ten and say several phrases, but otherwise--I know no Korean. Nevertheless, I can read. The Koreans are insular and paranoid. They are not imperialist expansionist, like the Inca, and they are not very good at socialism, like the Inca. They only have two things in common: collectivism and the rule of a despotic leader. But you could probably say that about a whole bunch of societies.
And what does any of this have to do with Obama and Islam?
