The shock Japanese assault on the US fleet anchored at Pearl Harbor on December 7, 1941 was a tactical victory however a strategic defeat, clearing the way in which for US entry into WWII. Historical past teaches that it was inevitable, however was it?
Over 2,400 Individuals died that Sunday morning as the first Air Fleet of the Imperial Japanese Navy, the dreaded Kido Butai, struck the Pacific Fleet at anchor on the Hawaiian island of Oahu. One US battleship, the Arizona, was destroyed outright. One other, the Oklahoma, broken past restore. Six others have been severely broken. A lot of the US airplanes have been destroyed on the bottom. At first look, “a date which is able to dwell in infamy” was a large tactical victory for the IJN, on par with the triumphs towards China in 1895 and Russia in 1905.
It was additionally a strategic catastrophe. The port amenities at Pearl have been left largely intact, so the US was in a position to rebuild and salvage many of the stricken ships. The US plane carriers have been elsewhere, which means they survived to battle one other day. Simply six months later, three of them would wipe out the Kido Butai at Halfway.
Extra importantly, the assault supplied President Franklin Delano Roosevelt with a rallying cry. He had been desperate to get the US concerned within the warfare in Europe, making a “Lend-Lease” program in March 1941 to produce the UK and later the us with weapons, and signing the Atlantic Constitution with British PM Winston Churchill in August. The vocal home opposition he confronted from Individuals unwilling to repeat Woodrow Wilson’s WWI journey vanished in a single day after Pearl Harbor.

‘Disaster of astronomical proportions’ over Pearl Harbor contamination
In recent times, there was a renewed curiosity in “alternate historical past,” such because the hypothetical world of Philip Okay. Dick’s “The Man within the Excessive Citadel” – tailored in a well-liked Amazon sequence – that depicted the US partitioned between Germany and Japan after shedding WWII. In that world, nevertheless, FDR had been assassinated in 1933 and Pearl Harbor by no means occurred as a result of it didn’t want to: the US had stayed out of the warfare till Germany and Japan acquired robust sufficient to invade outright.
Churchill himself dabbled in alt-history again within the 1930s, writing a notable account of a Accomplice victory within the American Civil Struggle. The Japanese choice to assault the US in 1941, nevertheless, doesn’t usually get the alt-history therapy, as a result of it appears inevitable given the circumstances. Way more is claimed each August, in debates on whether or not the US actually wanted to drop nuclear bombs on Hiroshima and Nagasaki, introduced on the time as revenge for Pearl Harbor.
Ever because it was forcibly introduced out of self-isolation in 1853 by US warships, Imperial Japan’s worldview was summed up by the expression “jakuniku kyoshoku”: “The weak are meat, the robust eat.” Japan modernized and have become an imperial energy in its personal proper, profitable wars first towards China, then towards Russia. Throughout WWI, Japan sided with the UK and later the US, choosing off German colonies within the Pacific. Within the 1930s, it created a shopper state in Manchuria and invaded China. In July 1941, nevertheless, FDR reacted to the Japanese occupation of French colonies – together with what would later turn out to be Vietnam – by imposing sanctions. Japanese property within the US was seized and Tokyo hit with an oil embargo. Disadvantaged of almost 90% of the oil wanted for his or her warfare machine, Japan might both again off or double down.
The US knew all too nicely concerning the Japanese naval doctrine of “Kantai Kessen,” decisive fleet motion. Historic precedents existed, too, within the 1904 assault on Russian ships in Port Arthur, and the battleship engagement at Tsushima.
The British service assault towards Italian battleships in Taranto in November 1940, which crippled the Regia Marina for the remainder of the warfare, ought to have been instructive as nicely. The Japanese actually took notes and utilized the teachings to their strike on Pearl. The Individuals didn’t. It’s potential the assault itself might have unfolded in any other case if they’d. US intelligence even had stories of an impending Japanese assault, however official historical past maintains they by no means reached Hawaii on time, as a consequence of bureaucratic error.

Is one other Pearl Harbor potential? The selection is America’s to make
Students have advised a Japanese strike on the Philippines won’t have stirred up as a lot American anger, and that’s in all probability true. However the US fleet was not in Manila, however at Pearl. In line with Japanese reasoning – which badly misunderstood each FDR’s warfare ambitions and American public opinion – warfare towards the US merely wasn’t winnable except they might knock out the Pacific Fleet in a decisive strike.
By the point Admiral Chuichi Nagumo was given the order to “climb Mount Niitaka,” the die was already forged. There have been nonetheless issues that might have modified the course of historical past, nevertheless. Had the US carriers stayed in port and been caught within the assault, that might have harm the Pacific Fleet way over the lack of the battleships. Nagumo might have additionally struck the port amenities – however had as an alternative retreated, reportedly fearing the lacking US carriers would launch a counterattack.
The final turning level that might have set historical past on a unique course got here on December 11, when Adolf Hitler declared warfare on the US. The choice was baffling, as Japan had chosen to remain impartial when Nazi Germany invaded the Soviet Union in June that yr. Nor did FDR point out Germany, when he thundered to Congress on December eight concerning the “treachery” of Japan.
On December 5, simply two days earlier than the Kido Butai struck Pearl, the Soviets had stopped the Nazi warfare machine on the gates of Moscow. From that time on, neither Japan nor Germany had any hope of truly profitable the warfare, no matter whether or not the US acquired overtly concerned – although that wouldn’t turn out to be obvious till a lot later.
In attacking Pearl Harbor 80 years in the past, the Japanese navy junta had hoped to create an empire spanning the Pacific. In the long run, they succeeded – besides such an empire turned out to not be theirs.
