We don't owe Japan anything. Why on earth, when the American middle class is collapsing and we are falling behind the world in the affordability of healthcare, is Japan's ability to surpass us supposed to be important to me? Do we get something in return? Like, if Japan will pay for a single payer healthcare system in the United States then fine, they can have bases. But otherwise, we aren't some geopolitical Jesus. There is no reason to sacrifice the United States so that other countries might out-thrive us.
