I will watch the entire series, but I don't view it as a real documentary about WWII. It is about individual perceptions of what was happening based on the personal experience of individuals who were participants but not movers and shakers in terms of the events. Burns uses these anecdotes to support his view of history, which is more subjective than objective. His view of MacArthur is somewhat one-sided.
at least those immigrants knew where there allegiance was...unlike today where you hear things like they cannot be separated from their homelands.
