What country is Norway's old enemy?

According to experience, it should be Sweden, because after all, two countries are adjacent to each other, and it is inevitable that there will be friction. Just like Germany and France, they are dominant in the euro zone, but they complement each other ~ ~ However, these two countries are peace-loving, so they will not be particularly competitive.

Sweden used to have a strong maritime power. I don't know if it has offended Norway. You can check it. Specifically, you can go to that Norwegian middle school student forum and ask.

I have seen many immigrants from the Middle East in Norway. Perhaps because of the unstable factors, the relationship between Norway and these countries of origin is tense, especially because the man thought that immigration was not good last year. This is purely my guess.
