The September 12, 2012 event was hosted by the Congressional Study Group on Japan of FMC (Former Members of Congress) (www.usafmc.org) and the Sasakawa Peace Foundation (www.spfusa.org).
Mr. Maehara starts out with offering condolences to the families of the US ambassador and others who was killed in the recent terrorist attack in Libya, and ends with reference to the 9/11 terrorist attack in the US 11 years ago, tying it with the 3/11 disaster that struck Japan last year. He delivered his speech in English.
I found the video in one of the retweets on Twitter, ridiculing his poor pronunciation of English, saying "See this pathetic video of Maehara, broadcasting his poor English to the whole wide world!" Well, I couldn't care less about the pronunciation. The speech has the substance, whether you agree with that substance or not.
He uses a capable American interpreter with excellent Japanese pronunciation in the question and answer session. I was reluctantly (as I'm not particularly fond of Mr. Maehara at all) impressed with the way he carried himself. Whether he understood English or not (I think he does), he listened attentively, nodding, and looking genuinely pleased to talk to these people.
His answers in Japanese is delivered in a slow, relaxed manner, without many cliches that other politicians like Prime Minister Noda craft their speeches with. He carries himself well.
I do see why this person is liked much within the US government circle. He looks like a normal human being that they think they can relate to. (I don't necessarily mean in a good way.) Despite the atrocious English pronunciation, I think his speech was attentively listened to. (I ended up listening to the entire video.)
