Um, actually the constitutional status of Wales is a murky topic, and even if that were to be cleared up unambiguously, how do you compare statuses across constitutions?
Wales is a constituent country of the United Kingdom and has some devolved power. However, it is the United Kingdom which is internationally recognised.
If Wales needs a tld, what about Texas? Texas has a distinct culture and was once an independent republic. I'm sure people from Wales think they are independent in some way that Texas is not, but people from Texas think those thoughts too.
Also, if Wales is already a country, why is independence the stated aim of Plaid Cymru :)?
