First: Continue the Kamikaze (air & sea) attacks. Very bad for morale and very expensive to the Allies.
Second: Human wave attacks against the Invasion by Civilian AND Military. Totally horrifying to troops AND home front.
Third: Exhaust the Allies resources and war morale. Britain had a new Labour government and with most of the rest, except Soviet Union (Russia) & USA, were economic basket-cases.
Fourth: Force a stalemate in 1946-8 and use Russia as a 'negotiator' for best terms which leaves Japanese Government whole. Russia had no real animus towards Japan and would cheerfully use its position to get Manchuria, Korea and the Kuril Islands. This would make up for the Russo-Japan War loss.
Excellent analysis and spot on. The combined mixture of what isn’t taught and what history has been forgotten will cost the Millenials dearly.
