Your comment contains several historical inaccuracies and simplifications:
-
Modern Austria as a state did not exist during the Napoleonic Wars, when Russia participated in anti-French coalitions. The Austrian Empire was then an active participant in the events.
-
During World War II, Austria was annexed by Nazi Germany in 1938 (the Anschluss) and effectively became part of the German state until 1945.
-
The term "Russia invaded Europe" is an oversimplification. The Russian Empire and the USSR participated in pan-European conflicts, but usually as part of coalitions and with specific political goals.
A more accurate historical position could reflect:
- Neutral status of Austria after 1955
- Austria's participation in pan-European institutions
- The complex history of relations between the Russian/Soviet state and European countries
I recommend avoiding simplistic interpretations of complex historical processes and interstate relations.
