Baffling geography

Dear Lupinion,
Is it true the Romania is really a country? I'm so baffled, can you please explain? Also, can you explain why Slovakia was a country during WWII but not before or after WWII?
Your ever loving reader,
Santa

Dear "Santa,"
You should not be going around acting like you’re all about the gifts for Christians and shit. What does Santa mean, anyway? Is that like some kind of saint with some kind of accent? You’re like a baby pirtz, man.
And you know who else hates you, Santa? My cat, she eats kibbles shaped like Santa, then poops them out and poops on them.
