It's still a misleading stat, The North Korean stats are essentially a "Total War" stat (as that reservist number is the ~ number of Males). To suggest that any countries are scared of another's simply by it's population is ridiculous. Let alone suggesting that "The West"s combined forces would be intimidated by that...
"Human Wave" [1] Tactics didn't work very effectively in the Korean war, they would work even less in a modern combat theater.
