I've recently read a few (mostly German-language) sources which mentioned that the Dutch considered to withdraw from the Caribbean during the 1870s and 80s to focus more on the subjugation of the East Indies. So what could bring the Netherlands to finally ditch the islands (which weren't that profitable anymore since the abolition of slavery) and sell them off.
Bonus points if Germany manages to buy the ABC Islands, which Germany wanted for naval bases.
