No doubt it would have been a logistical nightmare for Japan to say the least. Doesn't mean that the idea as presented is clueless though, it just means that the Japanese would have been clueless (given the logistical realities) to pursue such a course.
Myself, well I just wouldn't presume to know more about Japanese intentions at the time than the Japanese leaders did. I wouldn't have predicted Hitler's intent to try and exterminate an entire people on the scale he did either (hate, stereotyping, and bigotry of that magnitude are far beyond my reasoning), but it did happen. The question here is about intentions, not historical fact.
Nope, you can't believe everything you see on tv. But to throw a blanket over all PBS programming and treat it as a joke based on a single historical proposition from one show might be considered shortsighted, by some, to say the least.
I respect everyone's right to accept or reject anyone else's ideas, and that too, is a two-edged sword that we ALL must deal with.
