Because of Capitalism and Communism A country that had nothing in the conflict between the West and East was divided and it’s people divided for what’s going to be A century soon. What can be done to return korea into one whole country ? It’s economy ? Military Structure ?
Here some ideas any help for the Koreans
Korean reunification is possible there 4 or 5 factors needed just going to make possible. in 100 yrs it could be united because reality the situation with China is keyfactor. They must make A deal where they will see Asia interest first and not occident. Second they must use Economy it will be the the biggest factor to make it possible. Making household prices so cheap and encourage the public for unity. Propaganda , cinema , culture keep it up for 30 yrs and it will be 100 or 200 of billions of dollars wasted but for the cause it would work. Then third factor is technology it will be A double edge sword because the right tecnology must be used so the state does not become punitive and dictatorship but freedom based government exist like in the western countries.
Fourth deal must also made for the occident so the westernes can’t use it for war and make peace deals for China and USA. The fifth and crucial of this tactics I won’t say better later say it for it is vital information and will be very important.
Korean unification is possible but to be hasty and think it doesnt have too many tricks to make it possible and avoid nuclear war at all costs is not foolhardy. One day it will happen first G-d the koreans know it was the world banks that wanted the korean war against the soviet union it all ended bad and the korea had to pay the price.
It will be undone because technology changes everything.
