Talk about opening Pandora's box.
The problem with opening it--you can never close it again.
How will this affect the Cold War?
There will be a conspiracy theory that FDR knew about the Los Angeles attack and let it happen (if there is one regarding FDR and Pearl Harbor, there will be one regarding this attack).
I see large numbers of troops having to be recalled from overseas to suppress enormous race riots...
The hero is Hirohito...he might order Japanese doctors to help the victims, in return for Japan avoiding annihilation.
That's what I'm thinking too - once he realizes the scale of the retribution the Americans are capable of, he could very easily surrender & hand over Unit 731.
Would Tojo and his merry men accept such an order though? Even though the Emperor was divine they didn't seem all that obedient when push came to shove.
The hero is Hirohito...he might order Japanese doctors to help the victims, in return for Japan avoiding annihilation.
I still do not understand the reasoning of the Japanese. Let's see, "The Americans are coming closer and they are still mad about Pearl Harbor so let's make them even angrier by using germ warfare."
More like the Japanese failed to consider the mindset of American Exceptionalism. Rather than the USA being soft and scared of taking casualties, it's the US being not at all accustomed to putting up with aggressive action against itself, so they go apeshit easily.
Date: November 8, 1944
Location: Los Angeles (City Hall)
Time: 9:00 a.m.
The LACG met at city hall after a long night. By now two important facts were known.
A map of metropolitan Los Angeles was set up behind the task force. On it the locations of the bomb impacts were highlighted with white pins. Red pins indicated the residences of people who had already contracted the disease.
- Overnight 23 people had been admitted to local hospitals with symptoms indicative of bubonic plague.
- All of these people it was learned either lived near or had some contact with pieces of the bombs that fell on November 5.
During the next hour the LACG decided on several recommendations which would be made to the mayor’s office. First and foremost all police, fire, and medical personnel who had been summoned to any of the impact areas would report for immediate medical examinations with no exceptions. Second, all patients with the symptoms of plague would be moved immediately to isolation wards in their respective hospitals. Third, the elementary school where the child designated Patient 3 went was to be temporarily closed and the classrooms sprayed with insecticide to kill any fleas. Finally, all those with students at the school were to be asked to take their children to their family physicians immediately and to report any flu-like symptoms. Memorandum would be sent out to every hospital administrator warning them of the disease and how to take proper precautions to avoid spreading it.
A major issue was whether to inform the public or not. After a heated exchange between the mayor’s office and other members of the task group it was agreed that releasing information now would be better then letting rumor and gossip create problems later. A carefully worded announcement would be written up for the mayor to announce to the city later that night. In order to limit the possibility of the disease spreading to soldiers all leaves would be cancelled into LA until further notice.
One major issue was very troubling to the LACG. The disease had been active for at least 48 hours before anyone became aware of it. That meant that people from Los Angeles might already be carrying the disease to other parts of the country. The Ft. Detrick group would immediately be contacting Washington and requesting the Surgeon General’s Office to contact hospitals in major cities to be on the lookout for symptoms of bubonic plague. Doing so however would take a few days.
One good piece of news was that the fleas that had apparently been in the bombs would eventually die out and since the disease was endemic to the area already it was very likely after a brief period the epidemic would be over. The bad news was that no one knew how long it would take for the disease to run its course or how many would be affected before it did.
As the meeting concluded an aide came in and whispered to the head of the task force showing him a note. He briefly scanned it sighed and went to the map. He removed one of the red pins and replaced it with a black one. Henry Jennings designated Patient 0 had just succumbed to the plague. Sadly many more black pins would pepper the board before this was over.
The moment I saw this TL, I got pretty excited because this is my Master's thesis, Unit 731 and the American Intelligence Community. You are spot on about Donovan not knowing much about 731 in 1944, everything he was getting out of China and SE-Asia was totally second hand conjecture, nothing was ever concrete. I can imagine FDR demanding that Donovan get OSS agents into Manchuria to investigate the claims coming out of occupied China, but it's going to be difficult. Neither Donovan nor anyone in the OSS truly understood the magnitude of the Japanese bio-weapons program until the war was over. The first concrete evidence of human experimentation didn't emerge until September 1945 when Dr. Ishii and some of his associates began meeting with the technical and scientific research teams sent to Japan to study the advances that Japan made during the war.
The problem with 731 is that the delivery mechanism does not provide ample distribution of the plague-infected fleas to create more than a localized outbreak within the context of a modern health infrastructure. I can see a few thousand deaths, especially in the poorer neighborhoods, but even in China with an almost medieval medical infrastructure during the war in areas where open air tests occurred, no more than a few thousand people died. Now, Ishii's human experiments were beyond inhumane and were absolutely deserving of a war crimes tribunal hearing, but the US really walked away from its responsibilities and embraced these guys in hopes that they would give the US the kind of advantage in bio-warfare to offset any advances that the Soviets made.
In addition, you mentioned it in the last update, Bubonic plague is already endemic in the area around Los Angeles. In most of the southwest it's already endemic and had been brought over during the Spanish conquest. They have the health infrastructure to handle small-scale outbreaks, and at the time of this outbreak in 1944 Streptomycin is in the laboratory testing phases. Streptomycin is used in 1946 to treat pulmonary tuberculosis in a double-blind, but I'm sure that the guys from Fort Detrick know about this and might give the boys at Rutgers a call to rush production. Remember, Bubonic Plague is a bacteria and they've got some effective antibiotics to use and the good news is that with treatment the fatality rate drops to around 15%, which is pretty good, it's only with untreated Bubonic plague that fatality rates jump to 40-50%.
I've got a pile of research if you want me to forward it along. Most of it is a jumble of anecdotal stories collected after the war and half-completed investigations launched by OSS and military intelligence during the occupation.
