The Passing of Korea and Nuclear Power

"The Passing of Korea" by Homer B. Hulbert, an English missionary to Korea in the early 20th century, I recommend as a must read for the western mind to understand the culture and history of Korea and its current geopolitical situation. Witnessing the beginning of the Japanese occupation of Korea, beginning in 1905 after Japan defeated the Russians in a strategic battle for the peninsula, Hulbert concluded the Korea he knew would be complete subjugated and rebuilt in Japan's image.
Hulbert failed to learn however from his own observations. Korea had faced similar circumstances throughout its history and survived. Much of Korea's history was spent in offering tribute to China, whether it be Korean paper, highly valued, or women to serve as wives to Chinese husbands (this doesn't seem to be a new problem for China). China itself has often occupied Korea, and with its current leadership views Korea as its own territory, as it does Tibet, Taiwan and much of South East Asia.
In relation to North Korea, does China not have the ability to build nuclear power plants? In fact the United States, South Korea and even Russia are all offering to help North Korea meet its energy needs by building nuclear power plants, but not China. Currently it is reported that China is supplying North Korea with power, and many manufacturing plants in North Korea are limited to producing products exclusively for China. Technically, North Korea is producing power equivalent to its demand. This leaves nothing for development and most of the power is coming from plants along the Yalu River, bordering China.
Though North Korea has the fourth largest army, in the world it would be no match against China, considering China is in the best position to supply or deny North Korea of food. An army exists on its stomach. The impending annexation of North Korea will ultimately lead to the Chinese demand to reunify the peninsula, absorbing the South as it has Hong Kong and seeks to absorb Taiwan. In fact the United States, though it defends Taiwan, it does not recognize Taiwan as an independent nation nor is it a member of the United Nations as an independent nation.
One of the obstacles to allowing North Korea nuclear power plants was the possibility they may produce nuclear weapons. North Korea has removed that obstacle. One thing learned from Homer Hulbert's book is that Korea has historically displayed the art of playing surrounding powers against each other to their advantage. Yes, North Korea has only its own interests in mind, but there is a much larger picture besides the possibility of North Korea supplying nuclear weapons to terrorists, or an invasion of the South. It is a mistake to push North Korea into a corner with only China to turn to. Relations, especially those with the South should not be cut off.
