If it is true that the US military is buying dolphins captured in Taiji, it is an embarrassing international issue that must be addressed. But I suspect it is a politically motivated fabrication.
The Nikkei Asian Review is alleging that dolphins caught in the horrific dolphin drives in Taiji have been sold to the United States military.
There is no evidence cited, but the Asian Review is usually a credible source. It is suspected that this may be misinformation "leaked" from inside the Japanese government following the decision last month by the Japanese Association of Zoos and Aquariums to no longer purchase dolphins from Taiji to avoid suspension from the World Association of Zoos and Aquariums.
I seriously doubt that the US military is purchasing dolphins from Taiji, and it appears that the Nikkei Asian Review is simply using an allegation from an unknown source to undermine the credibility of US Ambassador to Japan Caroline Kennedy.
However as the Asian Review is a credible source, Sea Shepherd is looking into a FOIA request and will ask the US military directly if this is a credible story.
