National interests are key to understanding how countries interact and hold power in the world. Think of them as important rules that help countries make choices about their relationships and policies. Here’s how these interests change the way power works globally:

1. What Are National Interests?
   National interests include things like a country’s economy, safety, and cultural values.
   For example, if a country wants to make sure it has enough energy resources, it might form partnerships or even get into conflicts with others. This can affect stability in the region.

2. Real-Life Examples:

   • U.S. and Oil: The United States has had a big impact on politics in the Middle East mostly because it cares about oil. This was especially clear during the invasion of Iraq in 2003, where securing oil was a major reason.
   • China’s Belt and Road Initiative (BRI): China is investing in roads and other infrastructure in Asia and beyond. This shows its national interest in improving trade routes, boosting its economy, and gaining more influence.

3. Changes in Global Power:
   As national interests change—like with new technologies or the need to deal with climate change—power structures also change. For instance, as more countries focus on clean energy, they are rethinking their resources and alliances. This is changing how countries relate to each other.

In conclusion, national interests play a crucial role in shaping global power. They guide decisions and help form new partnerships around the world.
