The test-firing of missiles is nearly continual.
I'm pretty sure China (and to a lesser degree Russia) just gives North Korea these things because fireworks are always a good distraction. He hasn't fired anything really nasty and is just being annoying.
China is deeply involved because North Korea is an important historic buffer state. They also are generally mean to all their neighbours. I don't think that the government is capable of any moral decision making. Party first.
Russia is similar, but not quite as bad as they were when the USSR was still around. North Korea is more of a distraction for them. I don't like Putin, but he does seem to have some positive values, especially compared to the Chinese state. He also has bigger fish to fry on the other side of his country and his people are a lot freer.
Peace would be nice. I'm not sure if other powers would permit unification and I'm not sure if the North Korean government wants peace. The regime fears punishment but is relatively safe if they listen carefully to China and avoid annoying the USA too much. However, normal people want peace. South Koreans aren't all that afraid as they have gotten used to it. But it is sad to see and hear about the nightmare their cousins in the north are living through.
Remember the Berlin wall my friend? Families crying on both sides?
Remember the Roman Empire? The Ottoman Empire? The mighty Egyptian Kings?
Just a few examples how the world works through the ages and I do believe that one day the north and the south will be united.
Whether by war, peace or other means I do not know.
Sooner or later it will happen.
Blessings!
I do hope you are right.
I just hope when it happens it is united under Korea and no some outside force. True governance is self-determined.
There you go my friend. And you guys definitely don't need outside fingers in your pie. The thing must be sorted out between the two Koreas, and by nobody else. In the old colonial days, Portugal was in a war against Spain about colonies in Africa, England was at war with the Boers to claim the gold in our mines, and you can read in history how many countries had agendas whenever they became involved in "peace" offerings in other countries.
We pray for you guys.
Blessings
