Well then, i would have to say that either this conspiracy is false, or FDR was the worst strategist in history. Think about it this way, if FDR knew that there were multiple carrier fleets bearing down on pearl harbor. He knew that they would be doing a complete suprise attack. If FDR knew this he could've ambushed them right then and there. He could have taken down one of the greatest navies in history at that point in time. And no, you guys he was never willing to sacrifice two aircraft carriers. aircraft carriers are the most valuable warships in the world. Battleships are mere toys compared to what an aircraft carrier can do. Why do you guys think that the battleships are all but extinct by now? Now, considering that your arguement that FDR was a genius in his execution of this plan than we can assume he is not a moron. The aricraft carrier is too valuable. Take one of the carriers that avoided the attack, the USS Enterprise (not the space ship, but the WW2 aircraft carrier), it won more than thirty gold battle stars, a presidential award, the British Navies highest reward (to this day no foreign ship other than the Enterprise has won it) and uncountable individual awards to the crew. It is quite possibly the most famous ship in recent history, FDR was not willing to sacrifice aircraft carriers.
