There's nothing unique about Ukraine. Russia has already taken action against Georgia, and will continue to destablize the eastern half of Europe. You're either aware of this or you're in denial, which Germany obviously is. (Same people who made themselves dependent on Russian gas right before the Ukraine invasion, despite every warning to the contrary.)
It would help if you got your basic facts straight on Georgia, but to be fair this topic has been thoroughly retconned: the EU fact-finding mission reported that Georgia attacked Abkhazia and South Ossetia. They also found that the action that Russia took against Georgia was basically justified, but heavily disproportionate (they shouldn’t have made deep incursions into Georgia).
Another interesting fact: many countries, including in Eastern Europe were and are dependent on Russian gas. Ever heard of the Yamal pipeline?
