Regarding whether colonies should be regarded as the land of an occupying country, this is a complex issue involving historical, legal, moral and international relations. Here are some key points to consider： ### 1. **International law and the right to self-determination** According to international law, especially the Charter of the United Nations and the Declaration on Decolonization, colonial peoples have the right to self-determination, that is, they have the right to determine their own political status and future. This means that even if a colony has been occupied for a long time, the international community still recognizes the right of the people of the region to self-determination, rather than automatically treating it as the territory of the occupying country. ### 2. **History and Ethics** Historically, many colonies were occupied by force or unequal treaties. Even if the occupation lasted for a long time, the legitimacy and morality of this occupation were still questioned. The international community generally believes that colonial rule is an unjust historical phenomenon and should be resolved through peaceful means. ### 3. **Attitude of the international community** The international community usually does not recognize territories acquired by force or colonial means as legal territories. For example, the United Nations has passed a series of resolutions supporting the right of colonial peoples to self-determination and calling for an end to colonial rule. ### 4. **Reality and Politics** In reality, some colonies did reach some form of merger or independence with the occupying Power through peaceful or non-peaceful means after being occupied for a long time. However, this does not mean that the international community automatically recognizes the legitimacy of this merger, especially without the free expression of the will of the local people. ### 5. **Specific cases** Specific cases require specific analysis. For example, Hong Kong's return to China in 1997 was based on a negotiated agreement between China and the United Kingdom, which has been widely recognized by the international community. While some other colonies, such as Western Sahara, still have disputed status, the international community has not recognized Morocco's occupation of them. ### Conclusion Whether a colony should be regarded as occupying the land of a country cannot be judged simply by the length of time. International law, historical background, the will of the local people and the attitude of the international community are all important factors to be considered. Most importantly, the right of the colonial people to self-determination should be respected and guaranteed. Hope this answer can help you better understand this complex question.
