What if Unit 731 was more successful?

What if at some point between 1937 and 1945 Unit 731 succeeded in its goal in creating a lethal virus/bioweapon? (this may sound ASBish, but if the scientists were smarter or better equipped it could have happened) Take into account that Japan once managed to hit the West Coast in the war, albeit on an extremely limited scale and with no consequence--but this may now change.
 
Watch out!!!

I think it more likely that the Japanese would use their bioweapons on the Chinese. Initially that was the goal of their bioweapon program even going so far as dropping fleas infected with bubonic plague on certain cities in China. If they could create a real superbug, then it would be catastrophic for China. The only question is what measures would Japan take to inoculate her own troops against infection? The risk of infecting their own populace is just as great.
 
luck

It was pretty unlikely. I saw a documentry on the subject, though it was ambitious they were pretty backward. They might have caused an oubreak of known disease, or they could have gotten lucky and particularly deadly strain, something but it was unlikely considering their technique and resources.

They did get a lot of good medical research done. Helps that they could experiment on humans, the wonders of live vivesection.

What they would have done is caused a plague in China. They bit off a bit more than they could chew with Manchuria. They plain and simply didn't have enough manpower to solidify their gains.

I think that a plague in china would be similar to setting a fire. They might be able to get it to burn in the spots they want, but the chances of it getting out of control are high.
 
More on UNIT 731
http://en.wikipedia.org/wiki/Unit_731

Japanese scientists performed tests on prisoners with plague, cholera, smallpox, botulism and other diseases.[22] This research led to the development of the defoliation bacilli bomb and the flea bomb used to spread the bubonic plague.[23] Some of these bombs were designed with ceramic (porcelain) shells, an idea proposed by Ishii in 1938.
These bombs enabled Japanese soldiers to launch biological attacks, infecting agriculture, reservoirs, wells, and other areas with anthrax, plague-carrier fleas, typhoid, dysentery, cholera, and other deadly pathogens. During biological bomb experiments, scientists dressed in protective suits would examine the dying victims. Infected food supplies and clothing were dropped by airplane into areas of China not occupied by Japanese forces. In addition, poisoned food and candies were given out to unsuspecting victims and children, and the results examined.

the U.S. Troops capture japanese Soldiers with bioweapon vaccines.

but Bioweapon are uncontrollable
in Cold War they was only as see a last option or Doomsday weapon

so a more successful Unit 731 can end like this:
1945 a U.S."Dirty Dozen" vaccinated against bioweapon
for unusual and top-secret pre-invasion mission
find out if someone still lives in japan after bioweapon accident.
 
well woul;dn't that mean, if bioweapons from unit 731 were so much more effective against Chia's ppl and poss also US servicemen, that the murdering monster Shiro Ishii gets to swing at the end of a rope instead of being OTL pardoned to work for the US ?
