The whole asia is just a boling pot that is going to explode but nobody knows when. I predict the peak to be when the North Korean regime collapses and South tries to absorb the North de facto creating an option for Korea to become a regional military super house. Japanese right wing extremists pushing government to start massive military spending once again creating much more powerful Japan. I do not really know wha…
Can you detail your reasoning? If the lessons of West/East Germany are anything to go by, reunification will be followed by an inward looking period in which the work of integration absorbs all resources.
Also the Nork military while large, really wouldn't add anything to the capability of the South - it's poorly equipped, malnourished and badly trained. If it wasn't for the risk of collateral damage to Seoul, any modern military could rout it just as fast as Israel won the Six Day War or the Coalition rolled over Iraq in Gulf War 1.
