Even if Japan believes that spending money on young people is more appropriate than extending the lives of the elderly by a few years, the decision should absolutely not be to purchase large numbers of American fighter jets, but rather to use the funds to improve the birth rate, build infrastructure, transition to green energy, and support domestic industrial productivity. I cannot understand what purchasing fighter jets can do for Japan. Japan has in fact completely handed over its military sovereignty to the United States, and buying fighter jets is essentially just giving the United States a blood transfusion.
