If you ever feel like updating it to current scores, Eritrea would be replaced with Guinea-Bissau. Belarus and Moldova would be replaced with Kosovo and Macedonia. Albania would tie with Bosnia & Herzegovina. Samoa would be replaced by the Solomon Islands. Turkmenistan and Uzbekistan would be replaced by Syria and Yemen. Dominican Republic would be replaced by Mexico. Guyana and Argentina would be replaced by Bolivia and Peru.
Surely Eritrea should be number one, and how is Libya on it but not DRC, same applies to Uzbekistan and Yemen. And, really, how are New Zealand corrupt?
