Of Course there was prior knowledge of Pearl Harbor. I've never seen that document before but it doesnt surprise me. Think of all the benefits that the elites and the defense industry would get by starting another war. The main one was the fact that Wilson's League of Nations was totally rejected by the US, so the orchestrators of that organization had to try to make another world governing body. And what do you know, as soon as we get out of WW2 the United Nations is created, and the American People are more accepting of it because of the hackneyed notion that it will "end all future wars."

But look whats happened since then. The United Nations has been either involved in or directly the cause of every war that the United States has entered ever since WW2 ended. In fact, most of the "peacekeeping" operations that they are involved in end up killing more people than if they had just stayed out of it. Basically, although there was prior knowledge of a Japanese Attack on the US, it was allowed to happen because the elite bankers, defense industry, and promoters of world government needed it.
