"Be Prepared" isn't just the Boy Scouts' motto, it is also what military general staffs try to accomplish the world around. Case in point, The Telegraph (U.K.) reports China's leaked plans for a possible collapse of the neighboring North Korean regime.
Apparently the leadership in Beijing feels North Korea is unstable and could rapidly descend into chaos. China definitely wants to avoid hundreds of thousands of hungry, desperate Koreans swarming across their border looking for food and shelter.
South Korea should have made similar plans; I fear it may not have done so. Political consensus in South Korea may be inadequate for cold-blooded contingency planning.
