Um, the official narrative is the right one.
Let's look at what FDR did to provoke the Japanese. He cut them off from the supplies they were using to mass-slaughter the Chinese.
My complaint with FDR was that this should have happened in 1931 (okay, he didn't become president until 1933) when the Japanese invaded Manchuria. Japan was found to be in the wrong in the League of Nations, and they stormed out. That should have been immediately followed up with an international embargo on Japanese goods, a blockade of Japan with various Navies (The US and UK had a 3:1 Advantage over Japan in warships), until Japan withdrew.
The world turned a blind eye. They turned a blind eye again when Japan invaded the rest of China in 1937, engaged in the Rape of Nanjing. (or as Mike G. likes to call it, "The inappropriate touching of Nanjing")
You see, the real problem is that most discussions of World War II gloss over the part about the Second Sino-Japanese War. Nor do we hear as much about Japanese atrocities in China and the rest of Asia as we hear about German atrocities in Europe.
