Glad to have you helping, Sea of Japan. This isn't something to worry about though, I think we've got all the leaders up to date. (With the exception of Musharraf, Putin, and Zuma, who we are keeping for now). This list in the first post is old.
Here is the up to date list. These are the guys and gals who we presently have in the mod.
No harm in going over it.
We need some additional leaders I guess:
Norway: Jens Stoltenberg
Turkey: Recep Erdoğan
Morocco: Mohammed VI
West African States: Tandja Mamadou
Central African States: Antoine Ntsimi
East African States: Juma Mwapachu
Bangladesh: Sheikh Hasina
Mongolia: Sanjaagiin Bayar
New Zealand: John Key (former Minor Nations leader)
Bolivarian Americas: Should be Hugo Chavez
