Following the strong support from Jr. to re-establish the "Imperial Army", Japan unilaterally announced expansion of its territory. The vastly bigger territory covers UNOCAL oil wells on Chinese continental shelf and all the coastline at SE corner of S. Korea.
In retaliation, China cancelled export of all petro products to Japan. S. Korea passed a new law to confiscate real estate of pro-Japan citizens.
Jr. has provided 1 year GNP to Mongolia, $3B military aid to Japan, F-16 to India and Pakistan etc, not even counting Middle East.
