Did they ever pay "US" back dollar for dollar?
Did Japan ever pay back the 2.1 Billion Dollars the U.S. taxpayers spent ( $22 Billion in todays money) to rebuilt corporate Japan after they bombed Pearl Harbor?
This^^^^^^
Plus Japan's contribution to the United States does not come close to the amount we are and have been paying to protect Japan and have troops their and in that regions for decades, and decades to come - all after they attacked us in WWII. We have spent billions upon billions of tax dollars on Japan for defense and will continue to do so. And every time a Toyota vehicle is purchased, even if it its made here, the profit goes to Japan, never to return because we have a net trade deficit with them. So, if you think you are saying a big FU to GM because of their bailout by buying a Toyota, Nissan, etc., you are not and really need to look at the big picture.
