Nothing like that at all - it's quite simple: a name that is a collection of things can be 'The [collection of]'.

  - The Netherlands = The [collection of] lands that are 'nether' (=associated with reclamation from the sea, presumably)
  - The USA = The [collection of] states 
  - The UK = The [collection of] kingdoms
  - The USSR = The [collection of] soviet republics

The country called Ukraine is not a collection of ukraines, so it shouldn't be The'd. :)
