Doesn’t the book also include the Japanese attack on Pearl Harbor being a huge success ( oil reserves destroyed, sub pens and repair yard in complete ruins ).
The above was the original Japanese plan. Had they pulled it off and turned Pearl harbor into a waste land it would have been pretty hard to conduct the war from California.
the way I think the smart way for the axis to play it out was... when Germany had its packed with Russia then goes to war with England and France ... Japan also should have gone to war with England and France..
Germany basically follows the same exact scripted did in Europe up until when the switch gears and when after Russia
Japan at the same time in the Far East stays away from the Americans and goes after the British French and Dutch interest in the colonial region in the far east
This give Japan access to all the raw materials they wanted.... plus it can play to the American isolationist who didn't want to be involved in the war, American anti-colonialist sentiment, how can you justify going to war to defend British French and Dutch colonies...and the American Left who was on Hitler's and Axis side when he was allied with Russia.
Germany Japan and Italy basic could have taken all over all the other European colonial interests in the world.. including India ...
Britain being simultaneously hammered by the Germans in europe and the Japanese in the Far East Asian colonies .. and Germany and Japan leveraging the anti-colonial, isolationist, leftist sentiments in the US so the US could really not support Britain..the British Empire does in fact collapse.
once Britains out of the way now you have Russia sitting between Germany in the West and Japan in the East
If Hitler really wants his Russian showdown now he gets his Japanese allies to attack from the other side of the same time and they probably would take them.
make the whole thing a Eurasian, African, Australia war and keep the all the Americas out of the mix make them irrelevant via political maneuver
