Will Shifts In East Asian Demographics Impact Reactions To North Korean Aggression?

Relations between Seoul and Pyongyang are especially tense this month due to the annual "Foal Eagle" joint military drill conducted by the US and South Korea that will be held at the end of February. North Korea views these exercises as a provocation and has already threatened to cancel the proposed family reunions scheduled for February 20^th to the 25^th stating that "Dialogue and exercises of war" are incompatible. This comes at a time when Kim Jong Un is trying to consolidate his power with the recent execution of his uncle Chang Song-thaek providing an example of the brutality of this process.

When we look at the current tensions on the Korean Peninsula it is important to remember that North Korea has a history of taking action when the US military is in the region. For example the attacks on Yeonpyeong Island on November 23^rd, 2010 coincided with the Hoguk Exercises which were a joint Korean-US undertaking on the western shore of the Korean Peninsula. Last year’s drills were especially tense provoking North Korea to threaten pre-emptive nuclear strikes. Given the statements coming out of Pyongyang this year it is likely that tensions will be as bad if not worse. For these reasons some form of aggression from North Korea would not be unexpected. What is different this year is that the geopolitical climate of East Asia has shifted. This shift is attributed to numerous factors one of the most important of which is changing demographics.

Much of East Asia is facing a demographic crisis in which the population is aging rapidly while birth rates have fallen. Since 1978 China has had a one-child policy (which is now being reformed) and in the past few decades certain parts of Japan and South Korea have in many ways had a de facto one child policy due to a variety of reasons such as the high cost of raising children. 1984 was the last year that South Korea’s total fertility rate was 2.0. This metric has fluctuated between 1.1 and 1.2 for over a decade. Japan’s total fertility rate has not been 2.0 since 1974 and has ranged from 1.3 and 1.4 since 2002. From an economic standpoint this demographic shift is a challenge as the youth must provide more support to the elderly than in previous decades and the percentage of the population that can be classified as elderly is becoming much larger. This change is also forcing countries to stake territorial claims and make security arrangements now when they are in a position of relative strength.

From a security standpoint declining populations will mean a significant decrease in the number of people who are fit for military duty (immigration could mitigate this issue but at the present none of the countries in question are particularly keen on welcoming large numbers of foreigners). This dynamic combined with the reality that the US will not guarantee security in the manner that it has in the past are forcing China, South Korea, and Japan to shift their policies in a more aggressive manner. This change takes numerous forms such as the establishment of China’s Air Defense Identification Zone over a significant portion of the East China Sea and Japan’s efforts to build up its military. Such a situation increases the chance for conflict. In the past North Korea has been able to get away with a high degree of brinkmanship. Given the current geopolitical shift and evidence that Beijing is beginning to lose patience with Pyongyang it is not impossible that acts of aggression that in the past would only provoke condemnation might now produce more concrete action. For these reason we must be particularly concerned with East Asia this February. History provides us with countless examples of incidents that usually would have stayed minor but have become amplified due to social, political and economic changes such as a major shift in the demographics of a country. Though it can be a challenge to predict the exact form that a potential conflict will take we do know that major structural shift will usually increase tensions. Understanding the nature of these shifts better equips us to address these challenges.
