Debated a few months ago between myself and a few others I think the final decision was something around the 192 mark depending on how strict a definition you put on an independant country.
That was what the debate was all about the last time round......Wales is a principality....Norn Iron is a province....same as Monaco and loads of others....the 192 figure comes from the UN.
UN? HA! wouldn't trust them as far as i could throw them. they always get statistics wrong.
as for the link i provided it gives an actual listing of countries.
or just do what my granfather did and visit every country!
