Some historians believe FDR was aware of the Pearl Harbor ahead of time and allowed it to take place in order to have a pretext to enter the war, essentially starting WW2.
B) World War II started two years earlier than Pearl Harbor, when Hitler invaded Poland. The idea that FDR started WWII is the most ludicrous, revisionist idea I've ever heard about history.
2. My point is it's not really a "world" war without the US. Would've probably called it something else.
2. Adding a continent to a war is not the same as starting it. That's like saying that if the US entered the war in Ukraine, then Biden started WWIII.
The person who started the war is the person who invaded a sovereign neighbor to expand his empire.
The Chinese might disagree.
