Final answer:
Neocolonialism best describes the continued exploitation of former colonies by Western powers, supported by postcolonial and conflict theories which examine the impact of cultural and economic domination.
Step-by-step explanation:
The historical phenomena described in the question allude to the exploitation and domination of less powerful nations by Western powers, such as England and France, particularly during the colonial and postcolonial periods. The most relevant theoretical framework that describes this example is neocolonialism, a concept that explains continued exploitation by former colonial powers through economic and other forms of influence, even after the colonies have achieved political independence. Additionally, aspects of postcolonial theory and conflict theory are applicable here as they provide insights into cultural interaction, economic disparity, and power dynamics that arise from the historical context of colonialism.
