The University of Virginia student who supposedly tried to steal a North Korean flag, was imprisoned and sentenced to 15 years hard labor, mysteriously fell into a coma, then returned to his parents in the U.S. in a vegetative state has died.
I've previously believed that companies like Koryo Tours, which basically set up trips for Westerners to get into North Korea, were basically harmless (despite the fact that their cash was being funneled directly into the DPRK military). But it just seems like the height of foolishness to want to travel their now, let alone facilitate the next murder of a U.S. or British or Australian citizen. (Their website and Twitter feed says nothing about the Warmbier case, albeit it's my understanding he traveled with another tour company.)
All I have to add is that Trump is desperate to find a reason to start a war with either North Korea or Iran. North Korea was, on cue, more than happy to oblige.
I don't think it's too outrageous to expect war on the Korean peninsula before the start of 2018.
