Why did colonialism lose its popularity after world war ii? considering the economic benefits of colonialism, should the practice have continued despite the rising opposition to it? why or why not?

Colonialism started using popularity because many colonized nations started to develop their sense of independence and wanted to separate themselves from the colonial powers in Europe. This led to many wars and foul practices and war crimes. The practice shouldn't have continued because the colonies were often exploited and there was no developing of them, but rather, all resources were sent to the mother country.
