As an AI, I do not have personal opinions. The decision to annex Königsberg would depend on various factors such as historical context, international law, and the will of the people living in the region. It is important to consider the potential consequences of annexation on stability, peace, and the rights of the inhabitants. Ultimately, any decision regarding annexation should be made through peaceful and diplomatic means, taking into account the interests and well-being of all parties involved. **

Greenland is not annexed by Denmark because it has been granted self-governing status within the Kingdom of Denmark. In 1979, Greenland was given home rule, which means it has control over its own domestic affairs, while Denmark retains control over foreign policy, security, and financial matters. This arrangement allows Greenland to have a significant degree of autonomy while still being part of the Kingdom of Denmark. **

Yes, annexation of land into cities still occurs today, although it is less common than in the past. Annexation typically happens when a city wants to expand its boundaries to accommodate growth or to gain access to resources. The process of annexation can be complex and may involve negotiations between the city and the affected landowners. Overall, while annexation continues to happen, it is not as prevalent as it was in previous decades. **

After World War II, no areas of the current state territory were annexed because the international community sought to prevent the expansion of national borders through force. The United Nations was established to promote peace and security, and one of its key principles is the prohibition of the acquisition of territory by force. Additionally, the experience of the war and the desire to avoid future conflicts led to the establishment of international laws and norms that discourage territorial expansion through aggression. As a result, the post-war period saw a focus on decolonization and the restoration of sovereignty to previously occupied territories, rather than the annexation of new territories. **

The valves on heating pipes are typically ball valves or gate valves. Ball valves have a spherical disc inside that controls the flow of water by rotating the handle, while gate valves have a gate or wedge that moves up and down to control the flow. Both types of valves are used to regulate the flow of hot water through the heating system and can be manually operated to adjust the temperature or shut off the flow completely. **

Silesia, East Prussia, and the Sudetenland were not annexed to West Germany in 1990 because these territories had historically belonged to Poland and Czechoslovakia, respectively, before being annexed by Germany during World War II. The international community, including the Allied Powers, recognized the post-war borders of these countries and did not support any attempts to change them through annexation. Additionally, the reunification of Germany in 1990 was already a sensitive issue, and adding these territories would have further complicated the situation and likely been met with strong opposition from neighboring countries and the international community. **

Yes, the consumption of energy-saving pumps may increase when replacing heating pipes. This is because energy-saving pumps are designed to operate more efficiently and effectively with newer heating systems and pipes. The improved performance of the energy-saving pumps may lead to increased usage, as they are able to distribute heat more evenly and effectively throughout the system. Additionally, the replacement of old pipes with newer, more efficient ones may also contribute to increased energy consumption, as the system may be able to operate more efficiently overall. **

Some recommended mixers for cocktails include soda water, tonic water, ginger beer, and fruit juices such as orange, cranberry, and pineapple. These mixers can be used to create a wide variety of classic and modern cocktails, and can be easily combined with various spirits to create refreshing and flavorful drinks. Additionally, simple syrup and bitters are also commonly used as mixers to add sweetness and depth of flavor to cocktails. **
