Actually the Japanese attacked us because of their dependence on our oil.
True, but we weren't dependent on them for anything, and thus, had no impediment to interning them. Besides, we were at war with them and saner minds prevailed in those days.
Very true. I've always found it interesting that that dependence existed because their ambition was to impose a regional hegemony. Yet it was that very ambition which caused Roosevelt to cut off fuel and scrap metal shipments.
Which sets up the pseudo-paradox: they could have had all the oil and metal they wanted so long as they weren't expansionists, but they only wanted the oil and metal in the first place because they were expansionists...
To be exact, they attacked us because FDR cut off all oil and steel supplies to Japan. They depended upon the oil we supplied for 50% of their needs. They wanted to assure new oil supplies from Dutch refineries and oil fields in Indonesia and they wasted little time in doing just that.
