They screwed up Indonesia pretty big (Japan helped during WW2). Then they wouldn't give it up. However, Indonesia is doing alright.
Suriname is also a nice example. They got complete self-government after WWII, in the 1970s the pro-independence governments got a small majority in the Surinamese parliament. Since the Netherlands at that time were ruled by the most leftist government in Dutch history, they were very eager to give Suriname its independence. As a result more than half of the Surinamese population decided to move to the Netherlands, since they all had a Dutch passport. Even now there are more Surinams here than in Suriname. And they were absolutely right to come here. Suriname is a mess.
