All except for Turkey and Azerbaijan, neither of which is really in Europe.
Are Georgia and Armenia in Europe?
culturally, yes.
Uh, in what sense?
Christianity? (not to speak for him)
I assume so - not that that is a definition with a validity in excess of 0. Elseways Eritrea and parts of Kerala are European, while Bosnia is not. Which is obviously utterly absurd. These are remnants of Asian Christianity - as anybody with an inkling of the history of the Middle East would find obvious. (Much less obvious, because the territory in between was eventually Christianized at a surprisingly late date, because we've grown used to thinking of it as an unequivocal part of Europe for 300 years and more, and anyways it's had *some* ties to Europe long before, is that the same could historically be claimed for Russia.)
