The issue of colonies is a complex and controversial topic. From the perspective of history and international law, a colony does not automatically become the territory of a country even if it has been occupied for a long time. Here are some relevant considerations: 1. **International law and the principle of self-determination**: According to the Charter of the United Nations and many international conventions, national self-determination is an important principle. This means that colonized peoples have the right to determine their own political status, including whether to become independent countries, merge with the occupying country, or adopt other forms of self-government. 2. **Decolonization process**: Since the mid-20th century, decolonization has become a common goal of the international community. The United Nations established the Decolonization Committee to promote the legitimate rights and independence process of colonies. 3. **Historical and cultural differences**: Colonies often have significant differences from the occupying country in terms of culture, language and history, which also makes full integration as part of the occupying country more complicated. 4. **Diplomatic recognition**: Even if a country claims sovereignty over a colony, international recognition is essential. In many cases, other countries and international organizations may not recognize such claims. 5. Practical issues: Even if sovereignty can be claimed legally, practical issues such as governance, economic integration and social inclusion may still make such claims difficult to implement. In summary, a colony does not automatically become the land of the occupying country just because it has been occupied for a long time. Any changes involving territorial sovereignty usually need to be resolved through international law, the will of the local people and diplomatic channels.
