It is interesting that Sempill is regarded as a traitor when he did not imagine that his country and Japan would go into the war.
Thanks for posting that letter, Shinpachi; very interesting. This regarding Sempill as a traitor has come from misguided and poorly intentioned sources like that so-called documentary. Unfortunately the British press also picked up on that angle when the MI-6 documents were made public at the National Archive. Sadly, this is how the ill-informed public regard the situation and thus pay little thought to the truth. Its an attempt to use WW2 hatred toward the Japanese as some kind of reason for vilifying him and Frederick Rutland, which is incredibly insensitive of the press, but there you go.
