Sure that is old news, it happened a few days ago. What is significant is that unlike the 1950s the players have changed teams.
Russia called the North Korean's actions unacceptable!
Russia is not playing with North Korea. This is kind of a big deal. Most of the world seems to be leery of North Korea. There may never be another cold war or world war at least for many decades, but I think an economic war would be far more likely. The rules would be different but Russia and China would surely be big players.
In my mind this is kind of like Sony and Toyota becoming so very popular after the second world war. It is interesting to day the least.
