New Zealand - The one country on the world I would love to live in besides the Netherlands.
Gibraltar - Just because
Tunesia - A lot of history here
Somalia - A country filled with war, heroes could work here
Wales and Northern Ireland - just to have visit the entire UK.
Israel and Palestina - Terrorist stuff.
