Final answer:
Foreign domination threatened nation building through the exploitation of resources, cultural erosion, violence, and the spread of diseases, disrupting the social, economic, and physical well-being of the subjugated societies.
Step-by-step explanation:
Foreign domination was considered a threat to nation building because it often involved the exploitation of natural resources, the erosion of native values and ethos, the infliction of violence and mass killing of people, and the spread of new diseases in the country. These forms of domination undermined the economic foundation, social cohesion, and physical well-being of the subjugated societies. The colonial powers focused on extracting wealth, which depleted the natural resources and entrenched social and economic imbalances. Cultural subjugation went hand in hand with economic exploitation, as colonizers often sought to impose their own values and systems, undermining local traditions and social structures.
Additionally, the introduction of new diseases by foreigners had catastrophic effects on indigenous populations with no natural immunity, leading to widespread mortality and further weakening the stability and development of the society.
