I don't know where the "borders" (is Greenland in North America?) are but I would have guessed Norway to be closer than Netherlands and UK closer than Uruguay
Oh man, this is gonna take a while. Let's pretend that PAFF! Greenland disappears. Gone. It melted or something. Now, with what is left over in the world, Which countries starting with N and U are closest to North America?
Trinidad and Tobago to Uruguay is 2800 miles. Panama to Uruguay is 2900 miles. Newfoundland to UK is 2000 miles. The UK is closer to North America than Uruguay is.
