Wrong on both counts. He blaimed the west and the motivation for Pearl Harbor was an aggressive Japanese empire.
If you read the article carefully, you will see he was asked about motivation. He was not asked whose fault the attacks were. He was not talking about blame. You are also wrong about Pearl Habor. Some historians would even argue that the oil embargo was a deliberate provocation. If we are talking black and white and no grey areas blame, then Pearl Harbour was the Japanese's fault and the London attacks are the fault of those who planned and carried them out, but if you want deeper analysis of underlying causes, then you need to listen to what Ken said, because there is an element of truth in it.
