World War II and Cold War by Mark Felton Productions

  Interesting.  I knew there were plans for use of the I-400 class for an attack on the Panama canal and also of the Japanese bio-warfare operations but don't think I had heard plans for linking the two together.  Suspect he's over-estimating the impact even if all 10 a/c had been able to make attacks and talk of the 2 I's making their way into the Atlantic seems rather extreme.  Too many chances of something breaking down or simply them still being detected.  If nothing else a/c returning to the subs are likely to be tracked and the subs attacked before they could take them on board.

  The other factor of course is while it likely to cause a fair number of deaths and a lot of chaos and disruption its also going to really rile the US who at this time are already fire-bombing Japanese cities to ash.  They could easily use bio-weapons themselves in far greater numbers and the already partly starved Japanese population are likely to suffer much worse.  In this way its even possible that the war could end before nuclear weapons or Soviet intervention occurs but probably with markedly higher Japanese fatalities.

  Very interesting.  Had read some suggestions that Japan might try using such weapons in opposing an invasion of Japan itself but not for Iwo Jima.  It makes sense in one way as there is a strong concentration of US troops and there's less likelihood of infection spreading to the Japanese homeland.  Of course assuming that the US realise what's happened from the sudden appearance of multiple virulent diseases on a small island then there would be hell to pay. 

  Of course since one of the proposed infections was anthrax a possible US response would be to use a lot of that against Japan, which could be very nasty.  Especially given its so hard to eradicate.
