Interesting, especially as I'd have to say that events have proven both of you right from my perspective:

- soldiers gladly obeyed orders to essentially end all democracy

- soldiers mostly seemed to stop obeying their dictator's orders when they got confused about who's even in charge and what was legally standing rather than the public will.

- Yoon is not dead, not even imprisoned

Given all that mess, I can see aspects of both of your claims being true. It's quite interesting!
