The term you're looking is "sovereign state", not "country", which is messy because it can mean a subdivision within a sovereign state, e.g., England in the UK or Curacao within the Kingdom of the Netherlands. Likewise, "state" is messy as it can also mean a subdivision of a sovereign state, e.g., in the case of US states.//Slight hijack//
Trying to nail down a single, definitive definition of a "Country" is near impossible.
Somebody make me a concise set of objective criteria that includes:
The United States
The individual countries of Europe
Vatican City ("The Least Country Like Country That Is")
But doesn't include:
The individual US States
The European Union
The United Kingdom
Taiwan ("Errrr I mean Chinese Taipei which is totally not a country. *Whispers* Is China gone yet?")
Hong Kong ("The Most Country Like Country That Isn't" and "Hong Kong had a team in 2008 Summer Olympics in Beijing which doesn't make any kind of sense...")
But doesn't make an equally valid definitive country / not country declaration about:
Kosovo (Country or rebellious province of Serbia?)
Palestine (Having an opinion is a "Press Here to Start WWIII" Button)
Sealand or any similar "country."
As CGP Grey declared as his answer in his "How Many Countries Are There?" video the best is "to say about 200. To give a more definitive answer implies more agreement then there is because at the end of the day what makes you a country is other people agreeing you are a country."
(below, I'll just use "state" instead of "sovereign state").
If you go by the constitutive theory of statehood, i.e., that a state is only a state when it's recognized by all other states, the concept gets messy around the edges. There are plenty of even UN member states that are not universally recognized, e.g., Cyprus is not recognized by Turkey and until 2009, the Czech Republic and Slovakia were not recognized by Liechtenstein because the prince of Liechtenstein was pissed off they had expropriated some of his private property.
