It is a large difference, and he did not state it, probably because it undercut his narrative.
It is the main reason we got into WWII.
Pat Buchanan wrote a book in the 90s with an alternative view of history WRT Pearl Harbor and the events that led up to it. It was an interesting read. I don’t necessarily agree with him but there were things that he put a different light on that should be at least considered and how Roosevelt baited the Japanese, the way Blinken et.al. are baiting the Rooskies.
In any event, this will not end well for any of us.
