I don't know what you are talking about. Switzerland has about a thousand years of history as a state. And their ancestors have been on that location for about at least 500 more.
How did you get "they must be 6 months old"?
Also they are quite the peaceful people and have neutrality. It's not like Eastern Europe, where everyone owned a part or the whole country of their neighbours at some point.
Because you used the age of the nation as an excuse for fighting with their neighbors:
I can't expect people who have a 250 old country to understand that though.
But clearly it's BS. A country can be a thousand years old and not have any reason to fight.
There are clearly other problems in Europe.
