Go up from the balkans to the baltic states. Pass through Russia to the Caucasus states and then south.
Discussion
Yes (although you don't need to go quite as high as the Baltic states). Get a perfect score by naming the minimal number of countries in order to follow the broad path you outline. Requires good knowledge of the countries bordering the Ukraine (as you can't pass through it) but ppl who have followed the war should have mastered these by now.
Btw, last day to play this particular challenge. New challenge will drop tomorrow (Monday)
Yes you can go through Belarus to Russia, but seems more interesting through the baltic states 😀.
The route i would follow since i am in northwestern Greece would be Albania, Serbia, Hungary, Slovakia, Poland, ok Belarus, Russia, Azerbaijan, Iran, Iraq and then Saudi Arabia
