Josh Marshall makes a notable point regarding North Korea:
Talking tough is great if you can make it stick and back it up; it is always and necessarily cleaner and less compromising than sitting down and dealing with bad actors. Talking tough and then folding your cards doesn't just show weakness it invites contempt. And that is what we have here.
Um, yeah ... showing weakness. Now who around here might have made that kind of observation once upon a time?
