The definition of "country" which is used
when not having a philosophical debate about that definition.
1. Any of the nations of the world.
2. The land occupied by a nation.
1. A group of people living in a particular country,
forming a single political and economic unit.
2. A large number of people who share the same history,

in the same country).
If ~biggest~ assumes the number of individuals then
Country as nation may result in "Chinese".
Country as nation may result in "Soviet" Humans
having refused from national identification.
If ~biggest~ assumes the square of land occupied then
Country occupied by nation results in "Union of Soviet Socialist Republics"
occupied by Soviet Humans.
Country occupied by nation may also result
in "World" occupied by World Citizens
having refused from countries' borders acknowledgement.
