Most likely North.
China would assist North Korea in tbe war
The two Koreas are North and South Korea. We were divided into halves after a war. The war is not finished yet, we're just like taking a break. But nobody thinks the war would continue.
North Korea has recently declared that it is at war with South Korea. This is not really because of anything South Korea has done, but rather it is an attempt to pressure the international community which has recently enacted economic sanctions against North Korea, in an effort to discourage North Korea from pursuing its nuclear weapons program. North Korea cannot pretend to be at war with South Korea and still conduct business as usual with them. That would not make sense, and would show that the declaration of war is meaningless. Whether North Korea will take the next step, of actually invading South Korea, remains to be seen. If they do, then they will have a real war on their hands.
Probably if North Korea started a war, USA would go on and help South Korea for they are more friendly and because of similar government. China would help North Korea because of their similar government too. Japan would help South Korea because they are more of a close friend. Not because of a similar government. ---- if North Korea started a war, it would be my guess that USA, Japan, and China will help South Korea because North Korea is trying to send nuclear bombs to USA and other places.
south Korea and north Korea
South Korea- although the North now possesses missile technology sufficient to reach Japan and the North Western USA, South Korea is it's main target. They would start a war with South Korea first because they have been at each other for many years. If it would be a world war, then I don't know.
i think north Korea wants to start a war with south Korea
South Korea would now be dominated by communist North Korea
North Korea and South Korea are divided into a ceasefire line. This line made after Korean War.
The Korean war.
First, South Korea alone will not be able to win the war by themselves against the North. There were actually a plan ,or a senario, made by the USA, Bush Govt. First, South Korea will bomb the North and try to engage in a war state with the North Korea. By the time when the nuclear or whatever missile drops back in Seoul, South Korea by the North Korean, they would have not enough left then to attack to defend their country. Simply, later, USA will ally with South Korea and engage in a war too. By that time, North Korea will have no chance of winning the battle. After the war will be over, I probably think UN will take over the country and manage the land. That's about it.
North Korea attacked South Korea.
