Mmmm, well Dutch East India (nor Portuguese Timor) was an `enemy of the British empire´; on the contrary, it was invaded and conquered by Japanese forces just as Malaysia and Birma were.
(Singapore in fact was one of several Dutch possessions taken over by the British, like Sri Lanka and South Africa, during the Napoleonic era.) The only time the Netherlands were ever viewed as an enemy of the English was during the17th century Dutch Wars (known as English Wars in the Netherlands); needless to say that at that time there was no such thing as a British empire.
