This issue involves complex discussions at multiple levels, including international law, history, and real politics. Judging whether a colony automatically becomes the legal territory of the occupying power based solely on the "length of occupation" does not conform to the current international legal framework and the principles generally recognized by the international community. The following points can help understand this issue: 1. Legal principles: a. According to international law, occupation and transfer of sovereignty are two different concepts. Long-term occupation may strengthen a country's de facto control over a region, but this does not automatically grant it legal or permanent sovereignty. b. The concept of "acquisitive prescription" is generally not applicable to sovereignty disputes in international law, especially those involving colonies and occupied territories. International law emphasizes the principles of legal acquisition and self-determination rather than single de facto control or long-term occupation. 2. Self-determination and decolonization: a. The United Nations Charter and related international documents (such as the 1960 "United Nations General Assembly Resolution on Colonial Questions") emphasize that colonial peoples have the right to self-determination, that is, they should have the right to choose their own political status and future. b. In contemporary international relations, decolonization and respect for national self-determination have become mainstream values. Even if a region has been under the actual control of a country for a long time, the international community usually advocates determining the final political ownership through consultation, democracy or referendum. 3. Historical and actual cases: a. In history, there have indeed been cases where some countries have exercised administrative management over areas that have been occupied for a long time, but these cases are usually accompanied by international disputes and have not been universally recognized. b. Many cases show that the international community is more inclined to support the determination of territorial ownership through peaceful negotiations and legal basis, rather than simply using the occupation time as the only criterion. In general, although long-term occupation may shape a de facto state of control in politics and administration, in international law and international politics, it is insufficient and may even be illegal to determine sovereignty based solely on the "occupation time". All parties should follow international law, respect the right to self-determination of the people of the occupied territories, and the complexity of history to resolve this issue.
