I don't want to be off-topic either, but it bears mentioning that the Dutch Royal Family sought refuge in England; that the recognized government of the Netherlands was temporarily not in Holland; that the Dutch West Indies and the Netherlands East Indies and Dutch Guyana and Dutch Borneo all continued to be ruled by the free government of the Netherlands. So, yeah, it did exist in fact.
I agree-with cconstantine, that the Japanese were extremely foolish and displayed a complete lack of understanding of American politics when they attacked Pearl Harbor. In their ignorance, they did not realize that the moment they did that, they would lose all their Pacific territories, including the NEI, but everything else in SE Asia and China as well. A very, very bad decision.
The Japanese still don't have any natural resources; yet this tiny island has the third largest economy in the world. Amazing what you can do when you're backed into a corner without any military.
