This is a list of countries that can or will at some point join the EU and their current status on that path:
Acceding countries: Croatia
Recognized candidates: Iceland, Macedonia, Turkey, Montenegro, Serbia
Applied but not yet recognized as official candidate: Albania
Potential candidates that haven't yet applied for EU membership: Bosnia and Herzegovina, Kosovo
Countries that have either expressed a will to join the EU or could technically join at some point but aren't on EU's agenda yet: Lichtenstein, Norway, Switzerland, Andorra, Monaco, San Marino, Armenia, Azerbaijan, Georgia, Moldova, Ukraine, Kazakhstan, Russia, Cape Verde, Israel, Morocco
I was particularly surprised when i read that 81% of Israelis would support EU membership.
Anyways, vote away, and post your reasons.
Edit: No nation bashing and EU conspiracy theories.
