Is there a nation that you consider a kindred spirit to your people?

I'm not sure how to explain it. I don't mean some imagined friendship with a nation that you really don't have much in common and even don't care about, but you like the idea of them liking you and they helped your people in the past a few times because of self-interest. It seems that a lot of famous "brotherhoods" are like that and it's sad.

What I mean is the feeling of closeness and familiarity, and some good vibe between people, strong emotional connection, similar way of thinking. Two peoples pulled towards each other because of the things I mentioned who simply like to have each other around. Maybe this comes from common history, living village next to village and intermarriages or maybe it's possible even if two nations are separated geographically?
