A little history/geography quiz

[CGM]

Russia is indeed the obvious one. OK, to summarize, out of 15 current countries that were part of the U.S.S.R., we have 5.

Russia, Estonia, Ukraine, Uzbekistan, and Georgia.

p.s. I understand how tough this is. Myself I forgot that Georgia had been picked and had to look through the posts.

Ten to go.

edit: Armenia is correct, that's six.
