Regarding Hiroaki Sato’s Feb. 27 article, “Indefensible costs of military one-upmanship “: When it comes to national defense, Japan needs to accumulate human capital instead of participating in the arms race. In the 21st century, when many countries are locked in fierce competition to obtain natural resources, diplomatic issues related to national interests are flaring up. Every country that depends heavily on oil is beginning to realize that oil supplies will eventually be exhausted.
In this situation, Japan’s prosperity and security depend on whether it can get beyond oil. Japan, burdened with a heavy national debt, should not follow in the footsteps of other military superpowers. Instead, it should invest in human resources to shift into a new world of clean energy. If Japan distinguishes itself with new energy technologies, it will protect itself by restoring economic advantages.
