Historical nonsense
...to say nothing of their [Japanese] comparative backwardness in small arms and particularly armor, if not aviation and shipbuilding (at least at the outbreak of the war) is another.
You are egregiously misinformed or desperately hoping WE are. We're not.
The "comparative backwardness" produced the Zero, which was not seriously challenged in terms of performance until we developed the Corsair. The P-40 Warhawks and FM2 Wildcats were outgunned and Zeros could - and did - literally fly rings around each, especially the P-40. Our pilots developed techniques to address the Zero's faults (notably, lack of armor and self-sealing fuel tanks) and maximize their own plane's characteristics, but going into the war with Warhawks and Buffaloes, we were severely deficient.
The Japanese never developed larger tanks but, for the terrain the heaviest fighting was in and the forces they primarily engaged, did not really need them. It was only when they encountered the Sherman that Japanese tanks were at a severe disadvantage.
Neither is there anything wrong with the Arisaka rifle. Every country in the world EXCEPT the US armed its forces with bolt-action rifles and the Arisaka was accurate and reliable. Japanese PISTOLS
were garbage, however.
Our torpedoes were a
disgrace. Period. They would turn back on the launching vessel or fail to detonate on impact. The Navy, with the same incompetent, wilfull blindness that ignored the development of aviation, refused to acknowledge those defects. The result was many subs lost to their own torpedoes or sunk by the ships they attacked, or their escorts.
By comparison, the Japanese "Long Lance" torpedo was superior in EVERY aspect. It carried a bigger warhead at faster speed over a longer distance with greater accuracy. AND it actually detonated when it struck the target.
I would dispute the plausibility of Japan even assembling a theoretically sufficient force and getting it to the coast without it being mauled to the point of uselessness, let alone its fate were it to successfully establish a beachhead.
Then you continue to ignore historical fact to make baseless assertions.
FACT: The Pearl Harbor task force -
SIX CARRIERS, with all their escort vessels and oilers - sailed all the way from Japan to PH and was never spotted; the US Navy did not even know that fleet had left the home waters. Tell us again how an invasion fleet could not have hit US soil.
FACT: After Midway, the US Navy was confident that the IJN could not launch an attack for several months. Yet a cruiser group was not even spotted, still less engaged, until it literally blew through the Allied ships at Savo Island, inflicting a defeat so severe
the Navy covered up the story.
Revisionism is hard to pull off when the facts contradict the fantasy, isn't it........
