Was ist der Unterschied zwischen country und state und nation ?Du kannst auch einfach Beispielsätze geben.

Nation:
a place with a homogenous group of people (they have the same religion or ethnicities, for example). Iceland and Japan are nations. The US and Australia are not.
Similarly, Chechnya (in Russia) is a nation. It is a region that is inhabited mostly by the Chechen people even though it remains within Russia.

State:
a place that has its own government with complete control over foreign policies. A nation can be a state. Again, Iceland and Japan are both nations and state.

Country:
"Country" can be the same as "state" but its meaning is more ambigious (not everyone agrees on a definition). For me, I like to think of it as a state that is recognized by other countries. For example, ISIS is becoming more and more of a state because its government is quite powerful. However it is not a country since no government in the world recognizes it as a country.
