Hmm not that many then, I guess many of them have left already. 7 Irish against Russia and 0 for. Turkey had also ~30 against Russia, and 0 for Russia, while Spain had 0 for Ukraine but 20 for Russia. Somewhat interesting, it would be interesting to know how many of these volunteers had any Russian background.

In total when you exclude Russians there have been 'only' 2241 foreign fighters participating in the war, which sounds little to my ears?
