At the end of the 19th century, the new great powers such as the United States and Germany were trying to make up for the delay in the colonial race against the already consolidated colonial powers, England and France.
So they had as target of their plans and attention the colonies of the Spanish empire such as the Philippines, Cuba Puerto Rico and Guaam but meanwhile the Dutch with a colonial empire as large as the Spanish with the Dutch Caribbean, Dutch Guiana and mainly the Dutch East Indies what is now Indonesia was not even the target of attempts to take the Dutch colonies while the Spanish had their territories taken by the United States and Germany even planned to invade the United States to take the Spanish colonies,
While the Dutch being Germany's neighbors, even with territory as large as Indonesia were not even considered a target for US and German colonial expansion
Hey there,
Just to let you know, your question is fine, and we're letting it stand. However, you should be aware that questions framed as 'Why didn't X do Y' relatively often don't get an answer that meets our standards (in our experience as moderators). There are a few reasons for this. Firstly, it often can be difficult to prove the counterfactual: historians know much more about what happened than what might have happened. Secondly, 'why didn't X do Y' questions are sometimes phrased in an ahistorical way. It's worth remembering that people in the past couldn't see into the future, and they generally didn't have all the information we now have about their situations; things that look obvious now didn't necessarily look that way at the time.
If you end up not getting a response after a day or two, consider asking a new question focusing instead on why what happened did happen (rather than why what didn't happen didn't happen) - this kind of question is more likely to get a response in our experience. Hope this helps!
