It’s actually very reasonable, FDR knew the American public did not want to get involved. Churchill knew about it, we broke the Japanese code, these are facts not conspiracy.
The Japanese DIPLOMATIC code was broken before PH. No evidence that the IJN cipher had been broken until some time after. Specifics of the attack were not transmitted to the diplomats.
What FDR expected was an attack on the Philippines or another “Panay Incident”
There is no proof and those creeps who pretend there is are loathsome. Really loathsome. They appear serious, but in reality, are kooks who shouldn’t be seen in public. Someone or something did this. Actually, the allegations are quite treasonous. For decades, these kookisms have surfaced and there is still no proof and will be no proof. The pubic did not want to get involved like I did not know that. No doubt you are a 9/11 truther and no plane hit the Pentagon, either. Disgusting.
