Nations that can be compared to the US are many and wide from drastically different to slightly different.
Step-by-step explanation:
Nations around the world can be termed according to their difference from US in terms of culture and way of life along with demographics too.
The commonwealth countries like Canada UK Australia New Zealand are some of the ones that are very similar to US in that they share the languages and the dominant races there are white.
They are also culturally similar.
Other countries in Europe share cultural ties but are linguistically different in themselves and most people who live there are multilingual unlike the US.
This is also somewhat true for most of Asia.
