You have to go back over 200 years to get France invading Russia. Russia invaded Paris in 1813. Everyone invaded everyone in the 1800's. Russia was invading all its neighbors in the 1800's.
But the two republics are also recognized and did ask for help as well, hence the SMO- and idk what you would consider 2014-2022 in ukraine but civil war would be a fair description in my opinion.
