Passage: The original post-punk movement ended as the bands associated with the movement turned away from its aesthetics, often in favor of more commercial sounds. Many of these groups would continue recording as part of the new pop movement, with entryism becoming a popular concept. In the United States, driven by MTV and modern rock radio stations, a number of post-punk acts had an influence on or became part of the Second British Invasion of "New Music" there. Some shifted to a more commercial new wave sound (such as Gang of Four), while others were fixtures on American college radio and became early examples of alternative rock. Perhaps the most successful band to emerge from post-punk was U2, who combined elements of religious imagery together with political commentary into their often anthemic music.
What did bands associated with post-punk never turn away from?

Passage: The principles of imperialism are often generalizable to the policies and practices of the British Empire "during the last generation, and proceeds rather by diagnosis than by historical description". British imperialism often used the concept of Terra nullius (Latin expression which stems from Roman law meaning 'empty land'). The country of Australia serves as a case study in relation to British settlement and colonial rule of the continent in the eighteenth century, as it was premised on terra nullius, and its settlers considered it unused by its sparse Aboriginal inhabitants.
Imperialism is less often associated with which sovereignty?
