In German it is easier to tell from a nation and a country, in english it is not so.
The Word Nation refers to a group of people "who share common customs, origins, history, and frequently language" - in German we would use the word Volk. Country usually refers to a territory or region that is tied to a governmental body - in German we would use the word Land. I can be loyal to my people when not being loyal to my government, i.e. country. (or the opposite, which is not the case)
