I cribbed this on the internet and added some pictures and some of my comments to the article. This is a "What If" kinda thing.
If you can dishearten him or make the war too expensive for him, he is likely to cut you a deal just to get out of it.
Since Tokyo had no chance at the first option, they needed to aim for one of the next two possibilities. If they had managed their resources better, they could have narrowed the gap between the two sides. Failing that, they could have inflicted such heavy damage that the Americans would lose their appetite for the fight. Or, they could have opted to not confront the US directly and possibly kept them from joining the fight at all.
It’s probably true to say that that there was no single course of action that was going to lead to a Japanese victory. Their military leaders needed to act more strategically and less tactically.
What follows are five possible ways Japan could have won World War II. They are not exclusive. Actually, Japan’s best chances lay in adopting all five strategies. True, some of them are a lot more obvious in hindsight than they would have been to Japan’s leaders at the time, but we can debate their plausibility later.
Wage One War At A TimeIt is important for small countries to avoid taking on every other country at once. But Japan’s government was not established in such a way to allow civilian oversight over the military. Patterned after the German Imperial government, the power was entirely between the Japanese Army and Navy.
Without a strong emperor, the military branches were unmoderated in their jostling for power, constantly one-upping each other. The army was focused on conquering Manchuria in mainland China. The Navy was pushing to grab resources in Southeast Asia. By attempting both contradictory goals, Japan managed to surround itself with enemies. The Japanese government should have had set priorities. Then, it may have been able to achieve at least some of its goals.
Listen To Yamamoto
Admiral Isoroku Yamamoto is alleged to have warned his superiors that Japan had to win quickly and decisively to avoid waking the “sleeping giant” in America. He predicted that the Navy had six months to a year to impose its will before the Americans achieved full power in the Pacific. In that span, Japan needed to force the US into a compromise peace agreement that partitioned off the Pacific, giving Japan time to improve its defenses around their territories in the Pacific. If they failed, the US industry would crank out weapons in massive amounts while new ships would begin arriving in the Pacific. Yamamoto knew the American ability to behave against expectations and warned his superiors not to assume they knew how the US would act.
Don’t Listen To YamamotoWhile Yamamoto was proven correct in his strategic advice, he wasn’t as wise on the operational level. The way he saw to approach the problem of the superior US industry was to hit them in the core of their power – their naval fleet. The Japanese military leaders had long pictured themselves using “interceptive operations” to slow the US fleet as it headed to the Pacific, most likely to the aid of the Philippines.
Using planes and submarines, the Japanese Navy would reduce the size of the US operational fleet and the Japanese fleet would then engage in the ultimate battle. Yamamoto, however, convinced them to change the plans and strike a sudden blow at Pearl Harbor. His miscalculation was that the core power of the US fleet was not at Pearl Harbor but in the Atlantic and Pacific Oceans. All that Yamamoto’s actions could do, then, was delay the US entry into the war until 1943. The original plan appears to have had a better chance at success.
Concentrate Resources Instead Of Dispersing ThemSimilar to the way the Japanese could not seem to be content with fighting one war at a time, they couldn’t seem to stop themselves from multiplying their active operations and combat theaters. In 1942 alone, the Navy attacked the British Eastern Fleet off Ceylon in the Indian Ocean. They assaulted the Aleutian Islands. They opened a new theater in the Solomon Islands, which required defending a vast amount of ocean. Japan raised the cost of the war for itself when it had the fewer resources available, The National Interest reported.
Wage Unrestricted Submarine WarfareFor some reason, the Japanese navy did not instruct their submarines to attack any enemy vessel on the open seas between the US and the South Pacific. They should have realized that the US fleet had to protect an enormous amount of water just to reach the South Pacific. Japanese submarines were every bit as good as the Americans’.
They could have used them to make the Pacific shipping lanes impassable to US transports. It was the most direct way the Japanese could have exacted the heavy toll necessary to make the US consider withdrawing from the war.
The United States Navy did wage unrestricted warfare against the Japanese merchant fleet and this was done to starve the many garrisons that the Japanese had spread out in the pacific as part of the "whither on the vine". The Japanese had won tactical victories like at Pearl Harbor, but they were strategic failures. The Japanese were at the beginning of the war, far better trained and than we were, but that pendulum swung the other way the longer the war lasted. At the end of the war, the Japanese were sending barely trained pilots and crew against the battle hardened and experienced American Navy and Army.
