They were bled smashed and conquered totally. The victors perspective of history is crap, it is always crap. Both nations were reduced to slavery for the empire, both were recreated as firewalls against communism, one for Europe and one for Asia. They remain locked into that paradigm.
Okinawa, airbases, naval instalations, and troops all well within easy reach of the spoils of war. And by the way if the many bits of pre attack intelligence available to President Rosenfelt had been passed on to Pearl Command the Japanese fleet could have been sunk to a man before even one yankee had to die. War has been the best investment for at least five thousand years. All those souls at Pearl invested by their own government just to make war.
It's always flowers and candy with you ain't it. We both live in the same world but that is not at all apparent. I fear you have mistaken the dung for the rose.
You have an interesting but mistaken view of history. So far as the European Recovery Program (also known as the Marshall Plan) is concerned you are partly correct. Rebuilding Western Europe was seen a a bulwark against communism. There was similar thinking in terms of Japan. However, it was the way it was done that was most interesting. The US could simply have established non-democratic US puppet governments in both Germany and Japan. It chose instead to encourage the development of democracies. It succeeded so well in Germany that the present day German state is probably more democratic than the United States. So far as Japan is concerned the US replaced a warlike regime with one that is currently so pacifistic that rarely sends even peacekeeping forces overseas. The gracious manner in which the US treated a completely devastated and defeated enemy is without precedent in history.
I assume in your second paragraph your are referring to F. D. Roosevelt. The conspiracy rumour that he allowed the attack on Pearl Harbor is completely unproven historically. No one has been able to provide a shred of evidence that this was the case. You are also in error in believing that the US had military superiority in the Pacific in 1941. In fact the Japanese fleet, army, and air force greatly outnumbered the US forces in the Pacific and held that advantage even after the Battle of Midway. It was not until 1943 that US manufacturing capacity and its greater supplies of manpower overcame Japan's initial advantage.
