Rwanda. Sorry to torture you all with the letter A again. But there are no countries that start with the letter "R" that don't end with the letter "A". In this case, I picked the place of a horrible genocide over Mother Russia. Russia's just too weird.
oh, why thank you turbo nerd. Azerbaijan Edit: This should still be o. Oman, there's only one country beginning with o, and it's Oman... Oman.
