We’re broke and in extreme need to shift strategic manufacturing back to the U.S. instead of being reliant on other nations. Our national interests in Japan, South Korea and Taiwan are manufactured product based. We become more secure and economically prosperous by manufacturing the important things here. Over time we can drop the military protection with these countries. We can still be friends and we can still sell them weapons for their defense, but they can pay with their money. We can return our troops home so they can focus on the Constitutionally appropriate defense of America.
