It’s obvious by now… In a worse case scenario with someone triggering the whole thing it will be:
Poland, Ukraine, Slovakia, Czech, Croatia, BiH, Bulgaria on one side and Belarus, Russia, Serbia on the other side.
Result will be…well not good for either side, especially from the “Slavic” point of perspective.
Also Poland, Belarus and Ukraine will be the main areas were the conflicts might get ugliest and on balkans it’s the traditional Croatia-Serbia-Bosnia area too.
Okey maybe i’m overreacting but it seems really bad if the whole things starts up.
