Who is the real provocateur?

The 38th parallel was a convenient line drawn by foreign powers to divide Korea under their influence. First Korea was divided between Russia and Japan. When Japan defeated Russia, it took control of the whole Korea as its colony. After the defeat of Japan in WW2, the Americans and Russians again divided the Koreas into two at the 38th parallel. Failure to hold a general election to reunite the country led to wars between the two Koreans. After the Korean War ended in 1953, the 38th parallel again divided the two Koreas. The question is how did so many islands north of the 38th parallel ended in the hands of the South Koreans? After the war, China withdrew totally out of Korea. The US remained and made South Korea its semi colony, with military bases there. The superior US Navy must have taken advantage of the weaker North Koreans, likely without any navy, and occupied as many islands north of the 38th parallel as they could grab. That is why today, the Yeonpyeong and several islands are called disputed islands, snatched from the North by the South, like Diaoyutai, seized from China by the Japanese. The unbearable truth is made more painful with the South constantly conducting war games in these disputed islands that should belong to the North. An analogy would make this easier to understand. It is like Singapore being separated from Malaysia by the Causeway. And hypothetically, Singapore gained control of all the islands below Tioman and Kukup, with the support of the US. Then every now and then Singapore will conduct war games in Kukup or Pulau Aur or other islands in the east coast. Of course Malaysia will be furious and will warn of counter attacks. So who is provoking who? The situation in Korea is exactly like that. And the western media will keep pointing the finger at the North as irrational and belligerent. So who is the real son of a gun?
