While I wasn't thinking of a particular case, ISIS is certainly an instance of trying to cross the line.
(Which I suppose also further underlines the point I want to emphasize about how I'm trying to promote a food-for-thought question, not a value judgment. Personally I find ISIS contemptible as an organized crime mob, and I find them contemptible as a government. I have no plans to change my opinions based on which side of the line they fall on. Which one are they on, though? Honestly the answer probably varies by region at this point. You can make a case that Westphalian-style countries are dead in the Middle East, and a stronger case that they are at least trending down. Whether that trend will be permanent is anyone's guess.)
